AB  - Gold nanoparticles (AuNPs) have been investigated extensively in the past twenty years as a sensitizing agent in photon radiotherapy. Targeted delivery of AuNPs to specifc sites in cells and tissues contributes to highly localized radiation dose enhancement, whereby the surrounding healthy structures can be largely spared from the unwanted radiation efects. Te efciency of introduced AuNPs with regard to dose enhancement depends on the properties of the nanoparticles since not all of deposited radiation energy reaches the intended biological target but is partially absorbed within the nanoparticles themselves or distributed elsewhere. Te present paper investigates the infuence of AuNP shape and localization on the enhancement and intracellular distribution of deposited energy in radiation therapy with photons. Energy deposition patterns are calculated with nanoscale accuracy through Monte Carlo simulations of radiation transport, which are optimized to accommodate a structured geometrical representation of the region loaded with AuNPs, i.e., to allow discrete modeling of individual nanoparticles. Same-volume nanoparticles of three commonly encountered shapes—nanospheres, nanorods, and square nanoplates—are examined, in order to inspect the diferences in the propagation and absorption of secondary charged particles produced by the incident photons. Five diferent spatial distributions of spherical AuNPs at the single-cell level are studied in the simulations and compared according to the energy deposited in the cell nucleus. Photon energy, nanoparticle size, and concentration are also varied across simulation runs, and their infuence is analyzed in connection to nanoparticle shape and localization. Te obtained results reveal how the investigated nanoparticle properties afect their dose-enhancing ability and irradiation specifcity in AuNP-augmented radiotherapy.

AB  - The effect of gamma radiation on the reliable measurement of single voltage pulses of electron beam injectors into plasma during fusion experiments is considered in the manuscript. For this purpose, a 10 GHz fast voltage divider was constructed. The high-voltage capacitor was a gas condenser, and the low-voltage capacitor was a parallel connection of 10 mica capacitors. It turned out that the received radiation dose corrects the transmission ratio since it aligns the frequency characteristic of the mica in the area of spatial charge. This phenomenon has been explained from both a positive and a negative aspect with an effect on the concrete application. The need for further research on this problem was also pointed out to establish a saturation dose and thus obtain a constant frequency characteristic of the mica. The interest in the fast-divider behavior in the neutron field is also highlighted. © 2020 Informa UK Limited, trading as Taylor & Francis Group.

AB  - The second most important source of indoor radon, after soil beneath dwelling, is building material. With the increase in environmental awareness and new energy-saving policies, residents tend to replace the existing windows with tighter windows, which leads to a decrease in air exchange rate and consequently an increase in indoor radon concentration. In case of low exchange rates, dose caused by inhalation of radon and its progeny can exceed external dose originating from the radium content in the surrounding building material. In this paper, surface exhalation rates of radon ( 222 Rn) and thoron ( 220 Rn) from typical building materials used for construction and interior decoration of houses in Serbia were investigated. Surface exhalation rate measurements were performed using the closed-chamber method, while concentrations of radon and thoron in the chamber were continuously measured using an active device, RTM1688-2, produced by SARAD® GmbH. Finally, the impact of the replacement of windows on the indoor radon concentration was estimated.

AB  - The purpose of this study is to investigate and quantify the influence of nanoparticle composition, size, and concentration on the difference between dose enhancement values derived from Monte Carlo simulations with homogeneous and structured geometrical representations of the target region in metal nanoparticle-enhanced photon brachytherapy. Values of the dose enhancement factor (DEF) were calculated for Pd-103, I-125, and Cs-131 brachytherapy sources with gold, silver, or platinum nanoparticles acting as targeting agents. Simulations were performed using the Geant4 toolkit with condensed history models of electron transport. Stringent limits were imposed on adjustable parameters that define secondary electron histories, so that simulations came closest to true event-by-event electron tracking, thereby allowing part of the nanoparticle-laden volume used for calculating the dose to be represented as a structured region with uniformly distributed discrete nanoparticles. Fine-tuned physical models of secondary radiation emission and propagation, along with the discrete geometrical representation of nanoparticles, result in a more realistic assessment of dose enhancement. The DEF correction coefficient is introduced as a metric that quantifies the absorption of secondary radiation inside the nanoparticles themselves, a phenomenon disregarded when the target region is treated as a homogeneous metal–tissue mixture, but accounted for by discrete nanoparticle representation. The approach applied to correcting DEF values both draws from and expands upon several related investigations published previously. Comparison of the obtained results to those found in relevant references shows both agreement and deviation, depending on nanoparticle properties and photon energy. © 2020, China Science Publishing & Media Ltd.

AB  - The aim of this paper is to examine the energy and angular responses of thermoluminescent dosimeters containing either MTS-N (LiF:Mg,Ti) or MCP-N (LiF:Mg,Cu,P) detector materials, and of the InLight optically stimulated luminescent dosimeters containing Al2O3:C detectors. Ten radiation qualities, with mean energies ranging from 24 keV to 1.25 MeV, and five angles of incidence, between 0° and 80°, were used for this purpose. The dosimeter response measure of quality were the IEC 62387 requirements. The experimental results show that the MTS-N-based and the InLight dosimeters performed in line with the standard's criteria. On the other hand, the MCP-N-based dosimeters exhibited a pronounced under-response around the energy of 120 keV, which resulted in deviations from the standard's conditions for both the energy and angular responses. © 2019 Elsevier Ltd

AB  - The goal of the nanoparticle synthesis is, first of all, the production of nanoparticles that will be more similar in size and shape. This is very important for the possibility of studying and applying nanomaterials because of their characteristics that are very sensitive to size and shape such as, for example, magnetic properties. In this paper, we propose the shape analysis of the nanoparticles using three shape descriptors – elongation, convexity and circularity. Experimental results were obtained by using TEM images of hematite nanoparticles that were, first of all, subjected to segmentation in order to obtain isolated nanoparticles, and then the values of elongation, convexity and circularity were measured. Convexity C x ( S ) is regarded as the ratio between shape’s area and area of the its convex hull. The convexity measure defines the degree to which a shape differs from a convex shape while the circularity measure defines the degree to which a shape differs from an ideal circle. The range of convexity and circularity values is (0, 1], while the range of elongation values is [1, ∞). The circle has lowest elongation (ε = 1), while it has biggest convexity and circularity values ( C x = 1; C = 1). The measures ε( S ), C x ( S ), C ( S ) proposed and used in the experiment have the few desirable properties and give intuitively expected results. None of the measures is good enough to describe all the shapes, and therefore it is suggested to use a variety of measures so that the shapes can be described better and then classify and control during the synthesis process.

AB  - Following the requirements of radiation protection international standards, passive dosimetry systems are type tested, which includes the angular dependence. As it represents one of the most important dosimeter characteristics, the angular dependence of commercially available optically stimulated luminescent dosimeters has been examined in this paper. The empirically determined air kerma to the personal dose equivalent conversion coefficients decrease as the angle of incidence increases. It was anticipated that the dosimeter response would show a similar behavior. This expectation has been confirmed for all the used angles of incidence and energies of the primary X-ray beam, except for the 80° angle of incidence and the 33 keV and 48 keV mean photon energies, where an increase in the angular response has been observed.

They estimate the effective dose of occupationally exposed personnel, by measuring the ambient dose equivalent. A performance testing of a Geiger-Müller tube-based survey meter was realized in this paper. The energy and the dose rate dependence were determined for different thicknesses of lead tube wrappings, in order to achieve the optimal energy compensation. The energy response for higher-energy photons slightly improved by applying these filters, while it significantly worsened for low-energy X-rays. The angular dependence was tested in terms of angular response and its symmetry for different radiation qualities.

AB  - The variations in the threshold voltage shift in p-channel power VDMOSFET during the gamma ray irradiation was investigated in the dose range from 10 to 100 Gy. The investigations were performed without the gate bias and with 5 V gate bias. The devices with 5 V gate bias exhibit a linear dependence between the threshold voltage shift and the radiation dose. The densities of radiation-induced fixed and switching traps were determined from the sub-threshold I-V characteristics using the midgap technique. It was shown that the creation of fixed traps is dominant during the irradiation. The possible mechanisms responsible for the fixed and switching traps creation are also analyzed in this paper.

AB  - The sorption properties of waste facade, brick, and asphalt sample towards Sr(II), Co(II), and Ni(II) ions from single and multicomponent solutions were investigated. The highest sorption capacity was found for Ni(II) ions, while the most effective sorbent was facade. Simplex Centroid Mixture Design was used in order to investigate the sorption processes of ions from solutions with different composition as well as the competition between the cations. Based on the statistical analysis results, the equations for data modeling were proposed. According to the observations, the investigated solid matrices can be effectively used for the liquid radioactive waste treatment. Furthermore, the applied methodology turned out to be an easy and operational way for the investigations of multicomponent sorption processes.

AB  - Electronic personal dosimeters (EPDs) are increasingly being used alongside conventional thermoluminescent dosimeters to measure the dose of legal record in terms of personal dose equivalent. Therefore, it is of great importance to execute performance tests of these dosimeters in photon fields of various energies and at various angles of incidence. This testing is done in order to simulate the behavior of these dosimeters in realistic multidirectional polyenergetic ionizing radiation fields. Tests of accuracy, linearity, energy response, and angular response have been performed on 10 EPDs from multiple manufacturers. Various radiation qualities have been used in the energy range from 33 keV to 1.33 MeV and for angles of incidence 0 degrees to 80 degrees. This research proves that many of the EPDs tested performed according to the manufacturers specifications and the requirements of the international standards regarding personal dosimetry.

AB  - U radu je merena ekshalacija radona iz bigra iz Niške Banje poznatom po povišenoj
koncentraciji 226Ra. Bigar zbog svoje velike poroznosti i visoke koncentracije radijuma
je idealan materijal za testiranje parametara od kojih zavisi brzina ekshalacije. U radu
je razmatrana zavisnost ekshalacije u odnosu na vlažnost kao i na sprašenost uzorka.
Brzina ekshalacije je merena metodom zatvorene komore, a sama koncentracija radona
aktivnim uređajem. Dobijeni rezultati ukazuju da brzina ekshalacije raste sa povećanjem vlažnosti uzorka i smanjenjem veličine zrna.
AB  - In this contribution, radon exhalation rate from travertine originating from Niška
Banja, Serbia was measured. This particular travertine, with a high 226Ra concentration
and high porosity, is ideal for testing various parameters that can influence radon
exhalation rate. The radon exhalation rate was investigated for different sizes of grains.
Grain sizes were dived into 4 groups: 1) 2.1 - 1.6 mm, 2.) 1.6 - 1.2 mm, 3.) 1.2 - 0.7 mm
i 4.) < 0.7 mm. Influence of the humidity on radon exhalation rate was also
investigated. Samples with the smallest grain size were exposed to 3 different levels of
humidity (dry sample, and two samples in which water content was around 10% and
20% of the mass of dry sample. An accumulation chamber method with an active device
RTM1688-2 was used to estimate radon exhalation rate from continuous measurement
of radon in the chamber. Obtained results indicate that radon exhalation rate is
increasing with an increase of humidity of the sample and with an decrease of grain
size.

AB  - Determination of the angular dependence of thermoluminescent (TL) and optically stimulated luminescent (OSL) dosimeters is of great importance for their application in poly-energetic multidirectional photon radiation fields. In order to determine the angular dependence of the dosimeter responses for different photon energies, the dosimeters were mounted on an ISO water slab phantom, irradiated in two narrow beam X-ray qualities (N-40 and N-80) and in one gamma ray quality (S-Cs), defined in IAEA SRS 16. The angles of incidence ranged from 0° to 60°, with an increment of 20°. Two types of TL dosimeters were used: MTS-N (LiF:Mg,Ti) and MCP-N (LiF:Mg,Cu,P) and one type of OSL dosimeters, InLight (Al2O3:C). The two types of TL dosimeters have shown a similar deviation from their 0° responses for all the used radiation qualities, while the OSL dosimeters have shown a greater deviation from the reference values for the gamma radiation quality.

AB  - Prior to performing calibrations in the Secondary Standard Dosimetry Laboratory (SSDL), standard radiation qualities must be determined in order to accurately assess the absorbed dose of occupationally exposed personnel and to evaluate the performance of radiation measurement instruments. Due to the energy dependence of the calibration factor and the air kerma to the personal dose equivalent conversion factor, it is of great importance to properly establish standard radiation qualities. Radiation qualities can be characterized by determining their photon energy distributions, or by using the Xray tube voltage and the first and second half-value layers. In this paper, the half-value layers were determined by varying the thicknesses of the additional filtration absorbers. The calculated values show a deviation from the ISO standard values not greater than 6%.

AB  - With an increase in the awareness of the need to save energy, residents tend to live in dwellings with increasingly tight windows and doors, thus reducing the ventilation rate of indoor air which leads to an increased accumulation of radon indoors. Having in mind that a dose from an exposure to inhaled radon and its progenies can be higher than a dose received from radium in building materials, it is suggested that radon exhalation measurements should receive due attention. In this contribution, the authors compare results gathered using a few methods for radon exhalation measurement and discuss its merits and demerits.

AB  - The measurement results of ambient dose equivalent rate in an aircraft, performed by a standard portable dosimeter, at a non-commercial flight Belgrade - Podgorica at altitudes up to 9000 meters, are shown. By numerical interpolation of the measurement results, a functional dependency of the ambient dose equivalent rate on the altitude of the airplane flight is determined, obtaining a good agreement with the reference values. For commercial airlines in the Balkan region, total ambient dose equivalent, regarding the aircraft crew occupationally exposed to radiation in the course of a flight, was calculated and the maximum permitted number of flight hours per year, was estimated.

AB  - Manipulation of unsealed radiation sources in nuclear medicine (NM) departments involves non-uniform exposure to staff and high skin doses to the upper extremities from direct and scattered radiations. Conducted studies have shown that the annual dose limits could be exceeded and the continuous dose monitoring of NM workers hands is needed. The aim of this article is to show results of hand dose monitoring in terms of operational quantity H-p(0.07) for occupationally exposed NM workers to beta and gamma radiations in the largest NM centre in Serbia. Dose assessment was done by means of thermoluminescent ring dosemeters DXT-RAD (LiF:Mg,Ti). Monthly and annual doses were evaluated for a 5-y period (2010-14). Monitored NM staff was categorised according to the type of work, as nurses, radiographers, laboratory technicians and radiochemists. Performed evaluation showed that annual hand doses were within the annual limit for all staff categories, but further optimisation of working practice is needed.

AB  - Determination of the response of thermoluminescent and electronic personal dosimeters as a function of photon energy and angle of incidence has a crucial impact on their application in poly-energetic multidirectional photon radiation fields. In the experimental part of this paper, in order to determine the energy dependence of the dosimeter responses, the dosimeters were mounted on an ISO slab phantom, irradiated in X and gamma ray fields, defined in the IAEA SRS 16, within the energy range of 33 keV - 1,25 MeV. Tested dosimeters have not shown an adequate response in the low photon energies relative to their Cs-137 responses, while in the middle and high energy photon ranges they performed well and have shown a deviation relative to their Cs-137 responses up to ±20%. In order to determine the angular dependence of the dosimeters the N-200 narrow beam radiation quality has been used. The angles of incidence for which the dosimeters were tested range from 0° to 80°, with an increment of 20°. Most of the dosimeters have behaved as expected, except for certain dosimeters due to their significant increase in response caused by the influence of the scattered radiation.

AB  - The paper examines the effects of radiation on the electrical characteristics of monocrystalline silicon and germanium. Samples of monocrystalline silicon and germanium are irradiated under controlled laboratory conditions in the field of neutron, X- and gamma-radiation. Change of the samples specific resistance was measured dependent on the radiation dose with the type of radiation as a parameter. Next, the dependence of the samples resistance on temperature was recorded (in the impurities region and in intrinsic region) with the previously absorbed dose as a parameter. The results were statistically analyzed and explained on the basis of radiation effects in solids. The results are compared with those obtained by using Monte Carlo method. A good agreement was confirmed by the mentioned experimental investigation.
