AB  - U radu je predstavljena novoformirana baza podataka GRAMON (Ground Air Radioactivity Monitoring) koja sadrži rezultate merenja radioaktivnosti u vazduhu na sedam lokacija: Beograd (Srbija), Ljubljana i Krško (Slovenija), Sarajevo (Bosna i Hercegovina), Podgorica (Crna Gora), Skoplje i Bitola (Severna Makedonija). Iz baze su za sve lokacije preuzete mesečne vrednosti specifične aktivnosti prirodnog radionuklida berilijuma-7 i potom analizirani deskriptivni statistički parametri od januara 2010. do decembra 2019. godine. Srednje vrednosti specifične aktivnosti berilijuma-7 tokom ovog perioda kreću se od 3,32 mBq/m3 u Sarajevu do 5,93 mBq/m3 u Beogradu. Koeficijent varijacije najmanji je za Krško (37,7%) i Sarajevo (38,6%), a najveći za Beograd (54,8%) i Bitolu (72,4%). Ipak, 3σ-opsezi svih sedam vremenskih serija se preklapaju. U daljoj statističkoj analizi biće ispitano da li među ovim vremenskim serijama postoje značajne razlike.
AB  - This paper presents a recently established Ground Air Radioactivity Monitoring (GRAMON) database that contains the results of radioactivity measurements in the air at seven locations: Belgrade (Serbia), Ljubljana and Krško (Slovenia), Sarajevo (Bosnia and Herzegovina), Podgorica (Montenegro), Skopje and Bitola (North Macedonia). Monthly values of specific activity of the natural radionuclide beryllium-7 were selected from the database and descriptive statistical parameters were analyzed for each location from January 2010 to December 2019. The mean values of the specific activity of beryllium-7 over this period range from 3.32 mBq/m3 in Sarajevo to 5.93 mBq/m3 in Belgrade. The coefficient of variation is the least for Krško (37.7%) and Sarajevo (38.6%), and the largest for Belgrade (54.8%) and Bitola (72.4%). Still, the 3σ-intervals of all seven time series overlap. Further statistical analysis will investigate whether there are any significant differences among these time series.

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.

Dobijeni rezultati su u rasponu od 0.36 do 0.7, što je u proseku veće od preporučene vrednosti od 0.4.

Slaganje rezultata je testirano Z-testom koji ukazuje da ne postoji statistički značajno odstupanje između rezultata dobijenih različitim mernim uređajima, odnosno ne postoji nekonzistentnost između različitih metodologija merenja kao ni potrebe za harmonizacijom različitih procedura merenja.
AB  - In this contribution, the results of radon equilibrium factor measurement in selected dwelling and workplaces in Montenegro and Serbia are presented. Radon equilibrium factor was derived from measurements of indoor radon concentration and equilibrium equivalent radon concentration. Measurements were performed one day for each of 5 locations by using different active devices. Obtained radon equilibrium factors range from 0.36 to 0.7 which is in average larger than worldwide average of 0.4 Results are not surprising since measuring locations were kept closed during the measuring time, reducing therefore ventilation rate which as a consequence has an increase of equilibrium factor. Individual measuring results of indoor radon concentrations, equilibrium equivalent radon concentrations and radon equilibrium factors obtained with different detectors systems from 2 research teams was tested using Z – test. Obtained Z – score for each measurement vas below critical value, indication that there is no statistical difference between different measuring devices.

AB  - Sistematsko istraživanje radona u stalno nastanjenim stanovima u Crnoj Gori završeno
je krajem 2016. godine. Mjerenja radona su rađena detektorima tragova CR-39, u
trajanju dva puta po 6 mjeseci. Dobijeno je da je srednja godišnja koncentracija aktivnosti radona u stanovima u Crnoj Gori 110 Bq/m3
, a medijana 52 Bq/m3
. Prosječne
godišnje koncentracije aktivnosti radona u stanovima po opštinama kreću se od 40
Bq/m3
 (Budva) do 201 Bq/m3
 (Nikšić). U kvadratima mreže 10 km x 10 km, koja prekriva teritoriju države, prosječne godišnje koncentracije aktivnosti radona u stanovima
su u opsegu od 30 Bq/m3
 do 732 Bq/m3
. Srednja godišnja koncentracija aktivnosti
radona u stanovima urbanih područja (86 Bq/m3
) znatno je manja od one u stanovima
ruralnih područja (144 Bq/m3
). Takođe, srednja godišnja koncentracija aktivnosti radona u kolektivnim stambenim zgradama (51 Bq/m3

AB  - First systematic national radon survey in 1095 dwellings in Montenegro was finished by
the end of year 2016. Radon was measured with CR-39 nuclear track detectors during
two consecutive six-month periods. It is obtained that the national average radon
activity concentration in indoor air of homes in Montenegro is 110 Bq/m3
 and median is
52 Bq/m3
. The average indoor radon concentrations in the municipalities are in range
from 40 Bq/m3
 (Budva municipality) to 201 Bq/m3
 (Niksic municipality). The average
radon concentrations are also calculated for each of 131 squares of the 10 km × 10 km
grid which covers territory of Montenegro, and they are in a range from 30 Bq/m3
 to
732 Bq/m3
. In rural areas, the average indoor radon concentration (144 Bq/m3
) is much
higher than the corresponding one in urban areas (86 Bq/m3
). Also, the average radon
activity concentration in the single-family detached houses (119 Bq/m3
) are more than
twice higher than in dwellings of the large apartment buildings (51 Bq/m3
).

dva projekta. Prvi projektat IPA 2009 „Upravljanje zatvorenim radioaktivnim izvorima,
uključujući radioaktivne gromobrane“, je bio podržan od strane EU. Tokom njegove
realizacije uklonjeno je i transportovano u skladište 71 radioaktivni gromobran, 68
paketa sa radioaktivnim izvorima uključujući i 7000 radioaktivnih kompasa. Drugi je
bio Interegionalni TC projekat oznake INT9176 – "Jačanje kapaciteta kontrole
iskorištenih zatvorenih radioaktivnih izvora u mediteranskom regionu” (IAEA i EU),
koji je omogućio kondicioniranje izvora. U radu je prikazana realizacija ovih aktivnosti

AB  - During 2013 and 2014, all used radioactive sources, devices with closed radiation
sources, radioactive lightning rods, compasses, etc. were taken over, conditioned and
placed in a temporary storage for low and intermediate radioactive waste located
within the Center for Ecotoxicological Testing of Montenegro. These tasks were
realized through two projects. The first project IPA 2009 "Managing closed radioactive
sources, including radioactive lightning rods", was supported by the EU. During its
implementation, 71 radioactive lightning rods, 68 packets of radioactive sources
including 7000 radioactive compasses were removed and transported to the warehouse.
The second was the Interregional TC project labeled INT9176 - "Strengthening the
Control Capacity of Used Closed Radioactive Sources in the Mediterranean Region"
(IAEA and EU), which enabled the conditioning of sources. The paper presents the
realization of these activities as well as the results of dosimetric measurements.

AB  - The counting rates of the background double and triple coincidences at the PRIPYAT
spectrometer, with six NaI(Tl) detectors, registration geometry ~0.7x4 sr, and time
resolution for coincidences 40 ns, are considered in the work. Double and triple
coincidences in the energy range (200-3000) keV, in the whole region and in the energy
windows corresponding to the photo-peaks of gamma rays, which are registered in the
photo-peaks in the spectrometer integral and non-coincidence mode of counting only,
have been analyzed and discussed. Considered rays were ones with the energy 662 keV
(de-excitation of 137Ba, after b

b
-
-decay of 228Ac, in the 232Th series) and 1461 keV (de-excitation of 40Ar, decay of 40K).
Counting rates in the background spectrum, as well as in the spectra of 137Cs, 232Th and
40K after background subtraction, obtained by the detector duplets (angles ~90° and
~180°) and triplets of detectors capable to register double and three-fold gamma
coincidences, showed that the main contribution to the background double coincidences
was given by the photons scattered from crystal to crystal.

AB  - Gustina fluksa 222Rn iz tla, na površini suvog zemljišta, procijenjena je na osnovu
koncentracije aktivnosti 226Ra u zemljištu u Crnoj Gori. Na osnovu prethodno objavljenih
podataka i novih mjerenja, analizirano je ukupno 56 lokacija, i obuhvaćeni su svi regioni
(primorski, centralni i sjeverni). Mjerne tačke bile su u svim gradovima Crne Gore, sa
pogušćenjima u Podgorici (ukupno 13 mjernih tačaka), Nikšiću (12 mjernih tačaka) i
Mojkovcu (13 mjernih tačaka). Za 56 lokacija, koncentracije aktivnosti 226Ra u zemljištu
su u opsegu (11-216) Bq/kg, sa srednjom vrijednošću 41.3 Bq/kg. Procijenjene gustine
fluksa 222Rn na površini suvog zemljišta su u opsegu (0,005-0,077) Bq/(m2
s), sa srednjom
vrijednošću 0,013 Bq/(m2
s). Ova srednja vrijednost gustine fluksa radona iz tla ne odstupa značajno od srednjeg fluksa koji je procijenjen za svjetski nivo – 0,.016 Bq/(m2s), prema izvještaju UNSCEAR 2000. Analize za područja Podgorice, Nikšića i Mojkovca, pokazale su da je gustina fluksa radona iz tla najveća u Nikšiću (srednja vrijednost 0,018 Bq/(m2s)).
AB  - The flux density of 222Rn at the surface of dry soil was estimated using the 226Ra activity
concentrations in soils of Montenegro. Based on previously published data and new
measurements, 56 locations have been analyzed, covering all the regions (South, Center
and North). Measuring points were all over Montenegro, i.e., in all Montenegro's
towns, with additional sampling in Podgorica (13 measuring points, in total), Nikšić (12
measuring points) and Mojkovac (13 measuring points). For 56 locations, activity
concentration of 226Ra in soil was found to be in the range (11-216) Bq/kg, with an
average of 41.3 Bq/kg. The range of estimated radon flux density at the surface of dry
soil is (0.005-0.077) Bq/(m2
s), with an average value of 0.013 Bq/(m2
s). This average of
the radon flux density from the soil surface does not deviate significantly from the
estimated mean worldwide flux – 0.016 Bq/(m2
s), according to the UNSCEAR 2000
report. An analysis of the results for Podgorica, Nikšić and Mojkovac, showed that the
radon flux density from soil is the highest in Nikšić (0.018 Bq/(m2
s) in average).

AB  - Kvar u nuklearnoj elektrani u Černobilju 1986. godine proizveo je nuklearnu
katastrofu ogromnih razmjera, sa tragičnim posljedicama za ljude i živi svijet u
široj okolini elektrane i radioaktivnom kontaminacijom životne sredine na
ogromnim prostorima naše planete, koja još uvijek nije isčezla. Stoga je ova
katastrofa u javnosti izazvala strah od nuklearne tehnologije, pa je javnost i koristi
kao simbol opasnosti koja svijetu prijeti od nuklearki. Prva brojna mjerenja nivoa
radioaktivne kontaminacije životne sredine u Crnoj Gori počela su neposredno
poslije akcidenta. Međutim, tek od 1999. godine u Crnoj Gori se, kroz Program
monitoringa radioaktivnosti u životnoj sredini, realizuje sistematsko i redovno
ispitivanje sadržaja radionuklida u vazduhu, padavinama, površinskim vodama,
morskoj vodi, zemljištu, hrani i vodi za piće. U radu je dat presjek stanja sadržaja
137Cs u većini segmenata životne sredine Crne Gore, a takođe i prikaz trendova,
kao i nekih specifičnih slučajeva i pojava. Indikativno je da se u manjem broju
slučajeva, čak i 30 godina nakon černobiljskog akcidenta, pojavljuje relativno
visok sadržaj 137Cs u mesu, niži ali ipak izražen u mlijeku, dok je sadržaj u zemljištu
mjestimično na nivou neznatno nižem od prvobitno utvrđenog krajem 90-ih godina.
Sve ovo upućuje na opravdanost dalje realizacije Programa monitoringa
radioaktivnosti u sistematskom praćenju stanja životne sredine.
AB  - Malfunction in Chernobyl nuclear power plant in 1986 produced a nuclear
disaster of major proportions, with tragic consequences for the people and
wildlife in wider area of power plant and radioactive contamination of the
environment in the vast spaces of our planet, which has not yet disappeared.
Therefore, this catastrophe has caused public fear from nuclear technology, and
the public use it as a symbol of danger that threatens the world from nuclear
power plants.
The first numerous measurements of the level of radioactive contamination of the
environment in Montenegro began immediately after the accident. However, only
since 1999 in Montenegro, through the program of monitoring radioactivity in the
environment, is being implemented a systematic and regular monitoring of the
content of radionuclide’s in the air, precipitation, surface water, sea water, soil,
food and drinking water.
The paper gives cross-section of 137Cs content in most segments of the
environment of Montenegro, and also presentation of trends, as well as some
specific cases. It is indicative that in a minority of cases, even 30 years after the
Chernobyl fallout, appears relatively high content of 137Cs in meat, lower but still
expressed in milk, while the content in the soil in some places on level slightly
lower than the originally established at the end of the 90s. All this justifies the
further realization of the Program of radioactivity monitoring in the systematic
monitoring of the environment.

AB  - This paper deals with 137Cs activity concentrations in samples from the territory
of Novi Pazar (town core, Novopazarska Banja, Izbice). The measurements have
been performed in 2013-2016 using standard gamma spectrometry (HPGe)
procedures, and included samples of soil (11 locations), 11 individuals of
centipede (Scolopendra cingulata), vegetables (potato, onion), fruit (apple), as
well as “tree of heaven” Ailanthus altissima and pine Pinus sylvestris. The levels
of concentration/transfer factors for animal and plant species were evaluated,
together with corresponding radiation dose rate caused by 137Cs, and its
contribution to the total dose rate. All the samples showed relatively low level of 137Cs. Its contribution to the total external terrestrial gamma absorbed dose rate at
1 m in air at 11 measuring points did not exceed 11%, while the annual effective
dose caused by gamma radiation of 226Ra, 232Th, 40K and 137Cs found to be with
an average of ∼0.08 mSv y-1
, i.e., slightly higher than the global average annual
effective dose from natural radiation sources – external terrestrial radiation,
outdoors. The external irradiation of the considered animal and plant species by
the activity in soil was found to be dominant, and significantly higher than
internal exposure to incorporated 226Ra, 232Th, 40K and 137Cs. A contribution of
natural radionuclides to the total dose rate is many folds higher than that of 137Cs.
At the same time, upper levels of the total dose rates (external and internal
exposure) of S. cingulata, A. altissima and P. sylvestris to the terrestrial
radionuclides, are significantly below the threshold doses for terrestrial animals
and plants (1 and 10 mGy d-1, respectively).

AB  - The measurements of 239+240Pu and 238Pu activity concentration in soil samples
from Montenegro, together with 137Cs activity measurements in the same samples,
were used to determine the activity ratios enabling a discussion about origin of
these radionuclides, as well as estimating Pu isotopes level in soils at the territory
of Montenegro. The 239+240Pu/137Cs activity ratio was found to be with an average
of 0.020 and standard deviation of 0.007, the 238Pu/137Cs – with an average of
0.0006 and standard deviation of 0.0003, the 238Pu/239+240Pu – with an average of
0.030 and standard deviation of 0.007, confirming that plutonium isotopes, today
present at the territory of Montenegro, originated from the global fallout. These,
as well as the other results showed that 137Cs today present at the territory of
Montenegro predominantly has the Chernobyl’s origin. Based on 137Cs activity
concentrations in the Montenegro soils measured in the period 1994-2011, using
in situ and standard laboratory HPGe spectrometric method, levels of soil
contamination with plutonium isotopes have been evaluated and discussed – for
91 locations (67 – surface soil only, 24 – layers: (0-5) cm, (5-10) cm and (10-15)
cm). The highest measured 137Cs activity in top soils in 1994 was 740 Bq/kg, in
2001 – 1710 Bq/kg, in 2002 – 2011 Bq/kg, in 2011 – 413 Bq/kg, while the highest

AB  - The origin of 137Cs, whether it was generated as a global fallout or reactor
(Chernobyl) accident, is determined with assessment its relationship with 134Cs.
134Cs is artificial radionuclide, produced in nuclear power reactors, with a half-life
of 2.1 years. Since the data on 134Cs activity in Montenegro weren’t publish after
the Chernobyl disaster in 1986, there is no information about relation between
these two radionuclides and therefore its detection in the Montenegro’s
environment is not possible nowadays. Their detection (134Cs and 137Cs) and
separation with NaI (Tl) detector is aggravated with close energies of gamma rays
(605 keV and 662 keV), as well as with rays of close energies from natural
radionuclides, causing a need for the development of coincidence measurement
method. Using 2 detectors of spectrometer Pripyat (∼180°), 134Cs source is
analyzed in an integrated, non-coincidence and the mode of double coincidences.
This paper presents the results of the initial research for the establishment of
coincident detection methods and determination of artificial radionuclide 134Cs
activity in samples from the environment.
