AB  - This study reviews the performance analysis of a 137Cs irradiation system that has recently been installed in the laboratory of Uzbek National Institute of Metrology. The laboratory is responsible for calibrating calibration facilities and for calibrating most protection level radiation monitoring instruments used in medical, nuclear, industrial and academic settings in Uzbekistan. This system employs the most advanced radiation safety standards, along with 21st century source automation methods. In this work, we review the system’s performance according to ISO 4037 and present measurement uncertainty budget. Our analysis shows excellent results in terms of scattered radiation, beam uniformity and field size, change in source position, test for source impurities, chamber stability and source calibration, and all these parameters fully comply with the requirements of ISO 4037.

AB  - The European Association of National Metrology Institutes (EURAMET) within its research programme European Metrology Programme for Innovation and Research (EMPIR) funded project EMPIR 19NET03 supportBSS that contributes to the establishment of a European Metrology Network (EMN) for Radiation Protection (RP). The EMN-RP was established in September 2021 with the intent to work as a meeting point for the metrology community and all stakeholders in the field of ionising radiation regulation, thus providing quality assurance for measurements in each of the exposure situations contemplated in the European Legislation. Within project EMPIR 19NET03, work package 3 aims at the preparation of a Strategic Research Agenda (SRA) by identifying the metrology needs to support the European legislation and regulation in Radiation Protection and of two Roadmaps for metrology services, one under the European Council Directive 2013/59/EURATOM and the other under the EURATOM Treaty. Following a Gaps Workshop held in September 2020 and a second internal workshop that took place in April 2022, a questionnaire was prepared for distribution to the stakeholders, e.g. RP platforms and authorities, academia, industry, among other, together with an accompanying paper. In this paper, the authors present the state of the art of European legislation in RP, address the importance of metrology, the practices and activities that need metrology to meet the requirements set in the regulations, emphasise the need for quality assured measurements in all fields, highlight the stakeholders contributions in their specific area and show their vision of the EMN-RP.

AB  - Source strength measurements are of critical importance for brachytherapy and are often performed in hospitals using well-type chambers. Quality assurance and quality control procedures should be implemented, but that may prove difficult in some hospitals due to the lack of equipment or metrological support. A study was conducted to investigate the status of the measurement equipment in Serbian hospitals and to organize an intercomparison campaign using a hospital 192Ir source. All the hospitals were able to measure the source strength with the required accuracy, but the quality assurance can be improved. Two hospitals performed stability checks, which were evaluated. Uncertainty budget was created during the exercise and is presented in this paper. The described methodology can be used to quickly assess the performance of brachytherapy centers, and can be easily adapted to calibration procedure.

AB  - Since more than a half of the effective doses from all ionising radiation come from the exposure to radon and its progeny, radon is important in the field of radiation protection. Being a noble gas and therefore chemically inert, radon is also used as a tracer for different geological and atmospheric processes. Radon is of interest to climate scientists for monitoring greenhouse gasses (GHG). It is known that by knowing radon flux and variation of radon and GHG concentration at the same period of time during the night, it is possible to estimate emission of GHG. In this paper, the most important results of recently finished EMPIR project 19ENV01 traceRadon “Radon metrology for use in climate change observation and radiation protection at the environmental level” are presented. Project aimed to develop the capability to measure SI traceable radon activity in the range of 1 Bq m-3 to 100 Bq m-3, suitable for outdoor radon measurements, to develop the capability for traceable radon flux measurements in the field which is important for GHG emission estimates and validation of contemporary radon flux models. Within the project it was investigated to what extent radon flux and outdoor radon data could be used for estimation of radon priority areas.

AB  - Individual monitoring service at the Department for Radiation and Environmental Protection of Vinca Institute of
Nuclear Sciences performs individual whole-body and extremities monitoring of exposed workers, using thermoluminescent dosimetry (TLD) method. The dosemeters for eye-lens personal dose equivalent measurements,
Hp(3), are not regularly used at the workplaces in Serbia, even though the individual monitoring method is
accredited and available at the dosimetry service. Type testing of Hp(3) dosemeters based on LiF: Mg,Ti, placed in
modified ring holders was done following the changes in ISO 4037:2019 and IEC 62387:2020. The type testing
was done by varying radiation-based influence quantities: photon energies ranging from 33.3 keV up to 1.25
MeV, angle of incidence values of 0◦, 45◦, 60◦, 75◦, dose range from 0.05 mSv to 10 Sv. The results show that the
passive dosimetry monitoring system satisfies IEC 62387:2020 requirements in the mandatory range of influence
quantities, except for the lowest tested energy of 33 keV, when incident radiation angle is ±60◦ and higher.

AB  - Accuracy of measurement in individual dosimetry monitoring service is achieved by performing calibration of dosemeters, ensuring that the measured values are traceable to the primary standard for the quantity of interest. Even though a dosemeter can exhibit remarkable performance in the reference calibration radiation field (e.g. 137Cs), its performance can greatly differ under certain conditions. Effects of different influence quantities need to be examined to ensure that the dosemeters are reliable for use in a specific ionizing radiation practice. The most significant radiation characteristic influence quantities are the radiation energy, angle of incidence and dose (rate). International standards issued by IEC and ISO define radiation conditions and procedures for dosemeter type testing under effects of different radiation, environmental and mechanical influence quantities. Dosemeter performance is expressed in terms of relative response and is evaluated by comparing with defined limits of variation, taking into account the measurement uncertainty, according to [IEC 62387:2020, IEC, 2020]. A passive dosimetry system based on LiF:Mg,Ti thermoluminescent dosemeters (TLD) was tested for the effects of photon energy and angle of incidence in two dosemeter orientations, horizontal (up/down) and vertical (left/right), for the measurement of personal dose equivalent (Hp(10) and Hp(0.07)). The dosemeters were read out on the Harshaw TLD™ Model 6600 Plus Automated Reader (Thermo Fisher Scientific, USA), calibrated in 137Cs reference field. Low-energy X-ray reference field N-40, established according to ISO 4037-1:2019 [ISO 4037, ISO, 2019] and ±45°, ±60° angles of incidence were used to examine the passive dosimetry system performance. Limits of variation from -29 % to +67 %, defined in [IEC 62387:2020, IEC, 2020] for energy and angular relative response, were used for performance evaluation. The overresponses for Hp(10) for 45° and 60° were (51 – 62) % and (76 – 88) %, respectively. The results for Hp(0.07) for 45° and 60° were (66 – 69) % and (79 – 95) %, respectively. Thus, for both quantities it was observed that the criteria are met for the angle of ±45°, while for ±60° neither comply with the standard, for both dosemeter orientations, when uncertainties are taken into account. This shows that tested TLD system has high overresponse in low energy photon fields when larger angle of incidence values is encountered. The response could be improved if dosemeters are calibrated using appropriate reference calibration field or if different dosemeter holder is employed.

Low-energy X-ray reference field N-40, established according to ISO 4037-1:2019 [ISO 4037, ISO, 2019] and ±45°, ±60° angles of incidence were used to examine the passive dosimetry system performance. Limits of variation from -29 % to +67 %, defined in [IEC 62387:2020, IEC, 2020] for energy and angular relative response, were used for performance evaluation. The overresponses for Hp(10) for 45° and 60° were (51 – 62) % and (76 – 88) %, respectively. The results for Hp(0.07) for 45° and 60° were (66 – 69) % and (79 – 95) %, respectively. Thus, for both quantities it was observed that the criteria are met for the angle of ±45°, while for ±60° neither comply with the standard, for both dosemeter orientations, when uncertainties are taken into account. This shows that tested TLD system has high overresponse in low energy photon fields when larger angle of incidence values is encountered. The response could be improved if dosemeters are calibrated using appropriate reference calibration field or if different dosemeter holder is employed.",

AB  - Ionization chambers and solid state detectors incorporated into multimeters are often used for quality control in different modalities of medical imaging and diagnostic radiology. The equipment to be used in the routine QC procedures needs to be calibrated under well-known radiation conditions (known as radiation qualities) defined by the international standards. International standards IEC 61267:2005 [IEC 62167, IEC 2005] and IAEA TRS 457:2007 [IAEA TRS 457, IAEA 2007] cover general radiography and fluoroscopy radiation qualities (abbreviated as RQR and RQA series, in the voltage range from 40 kV to 150 kV), and computerized tomography radiation qualities (abbreviated as RQT series, in the voltage range from 100 kV to 150 kV), among other. In the field of mammography reference radiation fields are defined for molybdenum anode/filtration combination (Mo/Mo, abbreviated as RQR-M series, in the voltage range from 25 kV to 35 kV). Since Mo/Mo mammography units are widespread and available at hospitals they have been included in the standard [IEC 62167, IEC 2005]. Even so, Secondary Standard Dosimetry Laboratories (SSDLs) that are performing calibrations of QC dosimeters for end-users, rarely have availability of such anode/filtration combination under reference laboratory conditions. SSDLs most often employ X-ray generators with W/Al combinations. Additionally, nowadays many different combinations of anode/filtration are present in mammography units of different manufacturers that are commonly used in the hospitals. Multimeters are often sensitive to spectral changes caused by different anode/filter combination, so it is doubtful that the traceability established for one anode/filter combination can be used to measure doses for another combination. Measurements with different solid state detectors were performed under laboratory conditions with W/Al radiation qualities established in the SSDL. In the future, research will be expanded to clinical conditions in radiation fields produced by mammography units which employ Mo/Mo, Mo/Rh, Rh/Rh, W/Rh and W/Ag. Dosimeter response will be evaluated based on the dependency of 1st HVL which is correlated to radiation output of the X-ray generator (the incident photon spectra).

AB  - Clinical mammography units utilize compression paddle for breast compression during exposure. When compression paddle is released, it returns to a default position which varies between different mammography units. This default position is commonly used in quality control procedures. Guidelines for quality control testing in mammography propose measuring the half-value layer (HVL) by placing added filtration on compression paddle while multimeter is positioned on the mammography unit's detector. The influence of compression paddle positioning on HVL measurements was studied under laboratory conditions. The difference in HVL values with and without the presence of the plate is not insignificant, the positioning of the plate also has a significant impact on the measurements.

AB  - Supplementary comparison in terms of the ambient dose equivalent/rate was organized within EURAMET as a part of the DOSEtrace project, between 13 national metrology institutes and designated institutes. Calibration coefficients were compared for a secondary standard ionisation chamber for 3 X-ray and 2 γ-ray radiation qualities used in the field of radiation protection. Radiation qualities were established according to ISO 4037-1. Measurements were performed between 2019 and 2021. For the purpose of this comparison, it was considered that the reported uncertainty was confirmed if the relative deviation from the comparison reference value was smaller than or equal to the associated uncertainty. All the reported results by all the partners satisfied this criterium. Three participants were not able to perform calibrations in all mandatory radiation qualities, due to technical problems. The results are published in the Key Comparison Data Base (KCDB) of the BIPM as supplementary comparison EURAMET.RI(I)-S18. To reach the main text of this paper, click on Final Report.

Reliability and accuracy of dosimetry data acquired by passive dosimetry systems used for individual monitoring is assured by carrying out type tests. In this manner, the effects of different radiation influence quantities are examined. Passive dosimetry systems comprised of an LiF:Mg,Ti (TLD-100) detector card placed in two different holder models (8814 and 8850) and the Harshaw TLD Model 6600 Plus Automated Reader were tested. Type tests were done in an extended range of photon energies from 40 keV up to 1.25 MeV, angle of incidence values of ±45° and ± 60° for both vertical and horizontal dosimeter orientation, and in the dose range from 0.05 mSv to 1 Sv. Both dosimetry system configurations perform in line with IEC 62387:2020 within mandatory range for tested influence quantities. Dosimeters that use the 8850 holder type showed less pronounced energy and angular dependence of the response in the low-energy range.

AB  - Purpose: The recent update of the ISO 4037, in conjunction with the new radiation protection quantities introduced in ICRU Report 95, present significant challenges to calibration laboratories and industry. Furthermore, there is a need to address gaps and conflicts between standards that set requirements for photon dosimeters, and to incorporate upcoming and new technologies into standardization. Materials and Methods: The European Partnership Project 23NRM07 GuideRadPROS started in June 2023 and will address these issues in the next three years. The objectives are: • to develop harmonized X-ray spectrometry in accordance with the ISO 4037 standard series, evaluate discrepancies between measured and calculated half value layer of X-ray spectra, and produce data to update requirements for reference X-ray fields. • to develop guidance for the calibration of dosimeters. • to produce guidance on validated procedures for harmonized type testing based on IEC standards. • to assess future standardization needs and to produce a guidance document for the implementation of the new operational quantities of ICRU Report 95 into standards and regulations. • to collaborate with ISO and IEC and users of their dosimetry standards to ensure that project outputs align with their needs. Results: The outcome of this project will lead to improved and comparable procedures in calibration and type testing within Europe. Furthermore, the evaluation of the impact of the ICRU Report 95 quantities will allow for an informed realization of calibration fields. Conclusions: GuideRadPROS will improve the confidence in radiation protection dosimetry, both via the promotion of the implementation of the ISO 4037 standard series, and via the assessment of the impact of the ICRU Report 95 operational quantities on daily measurements in radiation protection.

abstract = "Purpose: The recent update of the ISO 4037, in conjunction with the new radiation protection quantities introduced in ICRU Report 95, present significant challenges to calibration laboratories and industry. Furthermore, there is a need to address gaps and conflicts between standards that set requirements for photon dosimeters, and to incorporate upcoming and new technologies into standardization. Materials and Methods: The European Partnership Project 23NRM07 GuideRadPROS started in June 2023 and will address these issues in the next three years. The objectives are: • to develop harmonized X-ray spectrometry in accordance with the ISO 4037 standard series, evaluate discrepancies between measured and calculated half value layer of X-ray spectra, and produce data to update requirements for reference X-ray fields. • to develop guidance for the calibration of dosimeters. • to produce guidance on validated procedures for harmonized type testing based on IEC standards. • to assess future standardization needs and to produce a guidance document for the implementation of the new operational quantities of ICRU Report 95 into standards and regulations. • to collaborate with ISO and IEC and users of their dosimetry standards to ensure that project outputs align with their needs. Results: The outcome of this project will lead to improved and comparable procedures in calibration and type testing within Europe. Furthermore, the evaluation of the impact of the ICRU Report 95 quantities will allow for an informed realization of calibration fields. Conclusions: GuideRadPROS will improve the confidence in radiation protection dosimetry, both via the promotion of the implementation of the ISO 4037 standard series, and via the assessment of the impact of the ICRU Report 95 operational quantities on daily measurements in radiation protection.",

AB  - Well-type ionization chambers are routinely used for measurements in brachytherapy departments. Since there is no calibration service for brachytherapy ionization chambers available in Serbia, Secondary Standards Dosimetry Laboratory (SSDL) in Vinca Institute of Nuclear Sciences started establishing this service, using a reference well-type chamber Standard Imaging HDR-1000 plus with a PTW Unidos Webline electrometer. The outer wall of the chamber is made of 20 mm thick aluminum, which reduces the influence of the scattered radiation. For each source there is a unique source holder for placement in a reproducible geometry inside the well of the chamber. The ionization chamber stability has to be checked periodically to ensure reliable measurements. IAEA Technical Report Series (TRS) 1274 [IAEA TRS 1247, IAEA 2002] gives guidelines on standardized procedures at SSDLs and hospitals, including the procedure for stability checks of welltype chambers. According to this procedure, 137Cs or 60Co check sources are inserted in the chamber well, using spacers or holders to achieve reproducible geometry. Measurements during stability checks should remain within ±0.5%. In this research, a different procedure for stability checks was tested. A teletherapy 60Co irradiator was used for external irradiation of the well-type chamber. All measurements were corrected for air density (ambient temperature and pressure). Measurements were done in a minimum scatter environment, which was achieved by positioning the ionization chamber 1 m from the irradiator, with the field size of 20x20cm. Correction for 60Co half-life was applied to all measurements. First, the influence of the source holders was tested, and no significant differences were found (0.16% maximum difference when holder is placed in chamber, compared to no holder present). All the subsequent measurements were performed without source holders. During the second test, 4 stability checks were performed during a period of 4 days without moving the chamber or irradiator. The deviations were within the interval -0.39% – +0.25% compared to the first stability check measurement. During the third test, 7 stability checks were performed during a period of 7 days, and complete setup was repeated during each check (chamber positioning, bench positioning, collimator setup etc.). The purpose of the second test was to check the repeatability of positioning, because the positioning can artificially increase deviations between subsequent measurements, making the chamber stability appear worse. All the results were within the interval -0.17% – +0.27%. The results show that this procedure can be adequate for the stability checks of well-type chambers, because the repeatability due to the changes in measurement procedures setup is better than the 0.5%. Differences between second and third test could be caused by insufficient thermalization of the chamber during the second test.

AB  - Quality Control (QC) measurements in diagnostic radiology are performed on a wide range of X-ray machines, used for different modalities such as radiography, fluoroscopy, mammography etc. Diagnostic radiology multimeters are in wide use in QC measurements [IAEA TRS 457, IAEA, 2007]. Many of these devices are based on several solid-state detectors positioned behind different filters, and values of different quantities can be calculated based on the signal from these detectors. Besides air kerma and X-ray tube high voltage, multimeters can often measure other special quantities, such as Half Value Layer (HVL), total filtration, irradiation time, product of current and time etc. Calibrations for these special quantities are very rarely available in Secondary Standards Dosimetry Laboratories (SSDL) or other calibration laboratories, so many end-users have problems to establish traceability. Research is currently being undertaken in Vinca Institute SSDL with the aim to establish traceability for HVL calibrations. HVL is a quantity that is commonly measured in SSDLs during internal QA/QC procedures, but there is no consensus on how to establish the traceability in SSDLs. Furthermore, measurement uncertainty for HVL is rarely estimated. In this research, HVL measurement procedure will be updated and detailed evaluation of measurement uncertainty will be undertaken. Sources of uncertainty that will be considered are: energy dependence of ionization chamber, thickness of aluminum filters, statistics of current measurements (reference chamber and monitor chamber), temperature, pressure etc. Traceable results of HVL measurements will further be used to calibrate and test multimeters in reference fields. In this paper, first results are presented.

AB  - Recommendations on diagnostic radiology calibrations are defined by the IEC and IAEA documents for molybdenum anode target material and molybdenum primary beam filtration (abbreviated as the RQR-M series). Calibration of diagnostic radiology dosimeters (ionization chambers and X-ray multimeters) can also be performed for other anode/filter combinations, including the tungsten anode / aluminium filtration setup. Performance of dosimeters can significantly vary in radiation fields defined by different anode materials and primary beam filtrations, where different spectra and first half-value layers are obtained for the same nominal X-ray tube voltages. Therefore it is important to calibrate or test dosimeters for the range of radiation qualities or conditions in which they will be used. Performance of two such detectors was evaluated.

AB  - Introduction
Calibration laboratories and industrial enterprises involved in radiation protection dosimetry face significant
challenges following the recent update of the ISO 4037 in conjunction with the new radiation protection
quantities introduced in ICRU Report 95, the gaps and contradictions in the standards that set photon
dosimeter requirements, and the lack of standards for upcoming and new technologies.
Methods
The European Partnership Project 23NRM07 GuideRadPROS launched in June 2023 will address these issues
over the next three years. The project objectives are:
1. to develop harmonized X-ray spectrometry in accordance with the ISO 4037 standard series, evaluate
discrepancies between measured and calculated half value layer of X-ray spectra, and produce data to update
requirements for reference fields.
2. to develop guidance and training material for the calibration of dosimeters.
3. to produce guidance on validated procedures for harmonized type testing based on IEC standards.
4. to investigate new and upcoming technologies and assess future standardization needs and to produce a
guidance document for the implementation of the new operational quantities of ICRU Report 95 into standards
and regulations.
5. to collaborate with ISO and IEC and users of their dosimetry standards to ensure that project outputs align
with their needs.
Results and Conclusions
GuideRadPROS will improve the confidence in radiation protection dosimetry, both by promoting the
implementation of the ISO 4037 standard series and by assessing the impact of the operational quantities of
the ICRU Report 95 on daily measurements in radiation protection. Furthermore, the outcome of this project will
lead to improved and comparable procedures in calibration and type testing within Europe

AB  - Purpose: The European regulation for protection against exposure to ionizing radiation is essentially laid down in the Council Directive 2013/59/EURATOM. The practical implementation of the European basic safety standards has become more complex due to the lack of consideration of the metrological implications and the adaptation to new technological developments. To overcome such a difficulty, a European Metrology Network for Radiation Protection (EMN RP) was stablished in September 2021 to act as a focal point between the metrology communities and the relevant radiation protection stakeholders, including regulators, standardization bodies, manufacturers, users of radiation sources and international organizations. Materials and Methods: In the work package knowledge transfer, the supporting project 19NET03 supportBSS, together with its EMN RP partners, EURADOS and the German Federal Office for Radiation Protection (BfS), organizes an international training course on dosimetry and emergency preparedness in collaboration with the UK Health and Safety Agency (UK HSA) and the Greek Atomic Energy Commission (EEAE) as local host. The course will be held at EEAE in Athens, Greece, from 18 to 21 September 2023. Webpage: http://www.ptb.de/tceurados-wg2-2023 Results: The aim of this course is to provide the theoretical background of dealing with emergencies and to enhance it with practical measurement exercises. The course consists of three days of lectures and discussions combined with one day of practical exercises in small groups of five people. Lecturers from different European institutes will present various topics from different perspectives. Conclusions: This paper evaluates the course content and the feedback from the participants. This course can serve as a basis for further courses that can then be offered by appropriate platforms.

AB  - The paper analyses the possibility of commercial neon indicator lamp at low pressure application as a gamma radiation detector. The diode is most often used as an indicator in electrical switchers. The analysis was performed on the basis of experimental electrical breakdown time delay data as a function of relaxation time, applied voltage and gamma ray air kerma rate. It has been shown that the indicator can be used as a detector for relaxation time greater than 70 ms. During this time period, a complete recombination/de-excitation of the particles formed during previous breakdown and subsequent self-sustaining discharge, which can further initiate next breakdown, takes place. It was also shown that gamma radiation leads to a significant reduction in electrical breakdown time delay for applied voltages close to indicator breakdown voltage. Based on the behavior of the dependence of the mean value of the electrical breakdown time delay on the gamma ray air kerma rate, it was shown that the indicator can be used very efficiently as a detector up to air kerma rate of 2.3 · 10-5 Gy/h, when the electrical breakdown time delay is measured for applied voltage 10% higher than the breakdown voltage. © 2023 The Author(s).

AB  - The purpose of this work is to assess accuracy and compare the performance of radionuclide calibrators (RNCs) used in nuclear medicine departments in Serbia. Testing of the RNCs included verification of measurement accuracy, as well as analysis of routinely used quality control protocols, by using the certified radioactivity standards (57Co, 137Cs). RNCs performances were assessed with 99mTc through comparison of reference value for radionuclide activity and RNC measurements. Results of the intercomparison revealed that RNCs, 15 in total, are accurate within 10% in vial geometry and within 15% in syringe geometry. Most of them showed similar performance. The results revealed that container geometry is an important influencing parameter in the accuracy of activity measurement. Obtained results indicate a need for regular calibration and implementation of Quality Control program in order to achieve and maintain the accuracy of activity measurements in nuclear medicine.

AB  - In accordance with ISO/IC 17025:2017 testing laboratory shall have a procedure for monitoring the validity of results that includes regular participation in interlaboratory comparisons. Interlaboratory comparison RADON2021 was organized in the frame of the bilateral project between Serbia and Montenegro: “Measurement of the radon equilibrium factor in typical residential buildings in Serbia and Montenegro and harmonization of radon measurement techniques” in order to assess congruence of different measurement techniques, and then harmonize methods in case of inconsistencies. Harmonization is of particular importance to neighboring countries, in order to avoid inconsistencies in the classification of radon risk zones along border areas. Thus, six regional laboratories took part in the intercomparison – three from Belgrade and one from Novi Sad, Serbia; one from Podgorica, Montenegro; one from Banja Luka, Bosnia and Herzegovina. All laboratories participated in the indoor radon measurements, while 4 laboratories measured radon in the soil also. The measurement methods and detectors used by the laboratories were: • for air - EPA 402-R-92-004 – Indoor Radon and Radon Decay Product Measurement Devices Protocols, ch. 3.1. with RAD 7, RTM1688-2 and RadonEye; EPA 520/5-87-005 – 1987 EERF Standard Operating Procedures for Rn-222 Measurement Using Charcoal Canisters, ch. 3.4 using adsorption on charcoal canisters; ISO 11665- 4: Measurement of radioactivity in the environment – Air Radon 222: Part 4: Integrated measurement method for determining average activity concentration using passive sampling and delayed analysis with Electretes, and • for soil gas - ISO 11665-11:2016 Measurement of radioactivity in the environment — Air: radon-222 — Part 11: Test method for soil gas with sampling at depth by using active devices RTM1688-2 and RAD 7. The measurements were performed in real conditions where the radon concentration varied following a typical daily variation. Indoor radon concentrations were measured at four locations, while radon measurements in soil were performed at one location, all at the Vinča Institute site in the period from October 1 to October 8, 2021. The exposure period was consistent with a typical soil and indoor radon measurement protocols. The radon concentration in the soil was measured at depths of 20 cm and 80 cm. The robust mean and robust standard deviation were calculated as the mean of all measured radon concentrations (excluding outliers) and their standard deviation. Reference values of indoor radon covered the wide range of concentrations: (65 ± 9) Bq m-3 , (519 ± 80) Bq m-3 , (900 ± 160) Bq m-3 , (1980 ± 160) Bq m-3 , while in the soil reference values were (13350 ± 780) Bq m-3 and (26100 ± 2400) Bq m-3 at 20 cm and 80 cm depth, respectively. In order to assess whether there is a statistically significant difference between individual measurement results and the reference value, the Z - test was used as a criterion for success. If, for the calculated z value, |z| < 2 the result is satisfactory, if 2 < |z| < 3 the result is questionable, while for |z| > 3 result is not acceptable. All results of indoor radon measurements were satisfactory, except in the case of one measurement (for the lowest reference value) with electret, that was at the detection limit. Three laboratories had satisfactory results of radon concentration measurements in the soil, while the results of one laboratory were systematically lower, with z <-3, which indicated the need for additional analysis of the causes of systematic error and the possible need to change measurement protocols and/or re-calibration of used device.

abstract = "In accordance with ISO/IC 17025:2017 testing laboratory shall have a procedure for monitoring the validity of results that includes regular participation in interlaboratory comparisons. Interlaboratory comparison RADON2021 was organized in the frame of the bilateral project between Serbia and Montenegro: “Measurement of the radon equilibrium factor in typical residential buildings in Serbia and Montenegro and harmonization of radon measurement techniques” in order to assess congruence of different measurement techniques, and then harmonize methods in case of inconsistencies. Harmonization is of particular importance to neighboring countries, in order to avoid inconsistencies in the classification of radon risk zones along border areas. Thus, six regional laboratories took part in the intercomparison – three from Belgrade and one from Novi Sad, Serbia; one from Podgorica, Montenegro; one from Banja Luka, Bosnia and Herzegovina. All laboratories participated in the indoor radon measurements, while 4 laboratories measured radon in the soil also. The measurement methods and detectors used by the laboratories were: • for air - EPA 402-R-92-004 – Indoor Radon and Radon Decay Product Measurement Devices Protocols, ch. 3.1. with RAD 7, RTM1688-2 and RadonEye; EPA 520/5-87-005 – 1987 EERF Standard Operating Procedures for Rn-222 Measurement Using Charcoal Canisters, ch. 3.4 using adsorption on charcoal canisters; ISO 11665- 4: Measurement of radioactivity in the environment – Air Radon 222: Part 4: Integrated measurement method for determining average activity concentration using passive sampling and delayed analysis with Electretes, and • for soil gas - ISO 11665-11:2016 Measurement of radioactivity in the environment — Air: radon-222 — Part 11: Test method for soil gas with sampling at depth by using active devices RTM1688-2 and RAD 7.

AB  - Radon flux measurements provide information about how much radon rises from the ground toward the atmosphere, thus, they could serve as good predictors of indoor radon concentrations. Although there are many different mapping methods with many different input data, radon flux data are generally missing and are not included for the delineation of radon priority areas (RPA). The aim of this literature review is to investigate to what extent radon flux was used, or could be used, for the delineation of RPAs. Numerous factors influencing radon flux were identified, but quantifying their contribution to radon flux measurement still remains a challenge. Different methods and measuring devices were used for the determination of radon flux, thus it is necessary to identify possible inconsistencies in order to harmonise different radon flux measurements. Due to the complexity of radon flux measurements, only two countries were identified to have performed national surveys on outdoor radon, which were of much smaller scale compared to those on indoor radon. A positive correlation between radon flux and radon quantities, such as radon in soil gas and indoor radon, indicates that radon flux could be used as an input parameter for the estimation of RPA. By reviewing radon flux models, it was concluded that up-to-date modelled radon flux maps have reached excellent spatial resolution and will be further improved, hence, they could serve as an input for the estimation and delineation of RPA.

AB  - Doses from the exposure to outdoor radon are typically an order of magnitude smaller than those from indoor radon, causing a greater interest on investigation of the latter for radiation protection issues. As a consequence, assessment of radon priority areas (RPA) is mainly based on indoor radon measurements. Outdoor radon measurements might be needed to guarantee a complete estimation of radiological risk and may help to improve the estimation of RPA. Therefore, authors have analysed the available literature on outdoor radon to give an overview of outdoor radon surveys and potential correlation with indoor radon and estimation of RPA. The review has shown that outdoor radon surveys were performed at much smaller scale compared to indoor radon. Only a few outdoor radon maps were produced, with a much smaller density, covering a larger area, and therefore putting doubt on the representativeness of this data. Due to a large variety of techniques used for outdoor radon measurements and requirement to have detectors with a high sensitivity and resistance to harsh environmental conditions, a standardised measurement protocol should be derived. This is no simple endeavour since there are more applications in different scientific disciplines for outdoor radon measurements compared to indoor radon.
