AB  - Istraživanja obuhvaćena ovom studijom predstavljaju prikaz efekata svojstava tla različitih poljoprivrednih koncepata na migraciju antropogenih radionuklida, 90Sr i 137Cs. Za potrebe ovog rada, izvršeno je uzorkovanje obradivog zemljišta na dve dubine na teritoriji grada Beograda tokom 2014. godine. U uzorcima zemljišta su određene fizičko−hemijske osobine i specifične aktivnosti ispitanih radionuklida. Radiohemijska analitička metoda je primenjena za određivanje sadržaja 90Sr, dok je specifična aktivnost 137Cs određena primenom gamaspektrometrijske metode. Ispitivanje efekata svojstava analiziranih uzoraka obradivog zemljišta na migraciju 90Sr i 137Cs, izvršeno je statističkim metodama analize. Primenom linearne korelacione analize utvrđeni su dominantni fizičko−hemijski parametri koji utiču na migraciju 90Sr i 137Cs u poljoprivrednom zemljištu.
AB  - The research included by this study presents the effects of soil properties of different agricultural concepts to the migration of anthropogenic radionuclides, 90Sr and 137Cs. For the purposes of this paper, sampling of agricultural soil at two depths on the territory of the city of Belgrade during 2014 was performed. The physico−chemical properties of investigated soil, as well as the specific activities of the mentioned radionuclides were determined. The radiochemical analytical method was used to determine the 90Sr content, while the specific activity of 137Cs was determined using the gamma spectrometric method. Examination of the effects of soil properties on the migration of anthropogenic radionuclides 90Sr and 137Cs, based on the analyzed soil samples, was performed by statistical methods of analysis. By applying linear correlation analysis, the dominant physico−chemical parameters that affect the migration of 90Sr and 137Cs in agricultural soil were determined.

AB  - Rezultati merenja radioaktivnosti zemljišta, mulja i vode u procesu iskopavanja bunara do maksimalne dubine od 13,5 m u selu Poganovu, u opštini Dimitrovgrad, prikazani su u ovom radu. Uzorci mulja i zemljišta, analizirani su spektrometrijom gama emitera i određivanjem sadržaja 90Sr. U slučaju uzorka vode, određena je ukupna alfa i ukupna beta aktivnost, i koncentracija radionuklida gama emitera. Pored navedenih uzoraka, sa iste lokacije su mereni i uzorci mahovina i lišajeva. Osim u uzorku mahovine i zemljišta sa dubine 0-10 cm u kojima je detektovano prisustvo 137Cs u veoma niskim koncentracijama za ovu vrstu uzoraka, ni u jednom uzorku nije detektovano prisustvo proizvedenih radionuklida, 137Cs i 90Sr. U slučaju prirodnih radionuklida, dobijene vrednosti koncentracija, karakteristične su za ovakve vrste uzoraka i ne razlikuju se u odnosu na druge lokacije na našim prostorima. Svi rezultati merenja ukazuju na to da se ova lokacija može koristiti kao nulta tačka monitoringa radioaktivnosti na našim prostorima.
AB  - The results of radioactivity measurements in the soil, sludge and water samples in the process of finding water and digging wells to a maximum depth of 13.5 m, in the village of Poganovo, in the municipality of Dimitrovgrad, are presented in this paper. Sludge and soil samples were analyzed by gamma-ray spectrometry and 90Sr measurements. In the case of water samples, gross alpha and gross beta activity, as well as content of radionuclides gamma emitter were determined. In addition, samples of mosses and lichens from the same location were also measured. Presence of the artificial radionuclides 90Sr and 137Cs were not detected in measured samples, with an exception of the sample of moss and soil from a depth of 0-10 cm, where 137Cs was detected in very low concentrations for this type of samples. In the case of natural radionuclides, the obtained values of concentrations are characteristic of these types of samples and do not differ from other locations in our area. All measurement results indicate that this location can be used as a zero point for monitoring radioactivity in our area.

AB  - Programom sistematskog ispitivanja nivoa radioaktivnosti u životnoj sredini na teritoriji Beograda predviđeno je merenje koncentracije radona (222Rn) u stambenim objektima, školskim i predškolskim ustanovama. Laboratorija "Zaštita", Instituta za nuklearne nauke "Vinča" je u periodu 2016-2020. izvršila ispitivanja u 547 prostorija (99 u stambenim objektima, 341 u školskim ustanovama i 107 u predškolskim jedinicama). Prosečna koncentracija 222Rn je iznosila 105 Bq/m3, a koncentarcija ispod 100 Bq/m3 je izmerena u 76,60 % prostorija. Vrednost od 400 Bq/m3 je prekoračena u 4,94 % prostorija. Od 15 beogradskih opština, koliko je pokriveno ovim istraživanjem, u 8 je detektovana koncentracija iznad 400 Bq/m3. Maksimalna izmerena vrednost u stambenim objektima je iznosila 3550 Bq/m3, dok je u vaspitno-obrazovnim ustanovama najveća detektovana koncentracija bila 1910 Bq/m3.

abstract = "Programom sistematskog ispitivanja nivoa radioaktivnosti u životnoj sredini na teritoriji Beograda predviđeno je merenje koncentracije radona (222Rn) u stambenim objektima, školskim i predškolskim ustanovama. Laboratorija "Zaštita", Instituta za nuklearne nauke "Vinča" je u periodu 2016-2020. izvršila ispitivanja u 547 prostorija (99 u stambenim objektima, 341 u školskim ustanovama i 107 u predškolskim jedinicama). Prosečna koncentracija 222Rn je iznosila 105 Bq/m3, a koncentarcija ispod 100 Bq/m3 je izmerena u 76,60 % prostorija. Vrednost od 400 Bq/m3 je prekoračena u 4,94 % prostorija. Od 15 beogradskih opština, koliko je pokriveno ovim istraživanjem, u 8 je detektovana koncentracija iznad 400 Bq/m3. Maksimalna izmerena vrednost u stambenim objektima je iznosila 3550 Bq/m3, dok je u vaspitno-obrazovnim ustanovama najveća detektovana koncentracija bila 1910 Bq/m3., The program of the level of radioactivity in the environment monitoring on the territory of Belgrade envisages measuring the concentration of radon in residential buildings, schools and kindergartens. The Department of Radiation and Environmental Protection of the Institute of Nuclear Sciences "Vinca" conducted examination in 547 rooms (99 in residential buildings, 341 in schools and 107 in kindergartens) in the period 2016-2020. The average concentration of 222Rn is 105 Bq/m3, and the concentration below 100 Bq/m3 was measured in 76.60 % of the rooms. The value of 400 Bq/m3 was exceeded in 4.94 % of the rooms. Out of 15 Belgrade municipalities covered by this research, a concentration above 400 Bq/m3 was detected in 8 municipalities. The maximum measured value in residential buildings was 3550 Bq/m3, while in educational institutions the highest detected concentration was 1910 Bq/m3.",

AB  - According to the current legislation in the Republic of Serbia, the radiological control of waste materials is performed at border crossings, as well as when there is an intention to dispose these materials in the environment. The gamma ray spectrometry is commonly used for determination of radionuclide content in waste materials. These measurements imply adequate sample preparation in order to achieve the desired measurement geometry for which the efficiency of the gamma spectrometer has been calibrated. Satisfactory homogeneity is often not possible to achieve in the sample preparation process. Also, the matrix of the measured material in most cases does not correspond to the matrix of the standard used for efficiency calibration of the spectrometer. For these reasons, it is necessary to make certain corrections to the measurement results (efficiency transfer, for example), as well as to expand the measurement uncertainty budget. The paper presents in detail the procedure for assessing the contribution of inhomogeneity of the sample to the measurement uncertainty, as well as the contribution that the efficiency transfer and coincidence summing corrections introduce to the measurement uncertainty budget.

AB  - Various imported building materials commonly used in construction and industry in Serbia were analyzed using gamma spectrometry. Based on the activity concentrations of 226Ra, 232Th, and 40K in the investigated samples, radium equivalent activity, Raeq, absorbed dose rate, D, annual effective dose, DE, and the external hazard index, Hex, were calculated to assess the radiation hazard for people. The Raeq for most of the analyzed samples (416 in total) was lower than the maximum admissible value of 370 Bqkg-1 set in the UNSCEAR report. The absorbed gamma dose rate in air was found to vary from 0.030 mGyh-1 to 1.328 mGyh-1 which in some cases exceeded indoor dose rates in Europe. The obtained values for annual effective dose exceed the limits of 0.41 mSv given in literature for about 5 % of measured samples, while values of Hex were higher than unity for three samples of cement, eight samples of granite, and one sand sample. As a possible source of elevated effective dose, the radon exhalation from building materials was estimated using the parameters given in literature. The internal dose due to 222Rn exhaled from the building material was found to be up to nine times higher than external dose due to 226Ra content in some cases.

AB  - This review paper discusses the content of natural ( 40K, 238U, 226Ra, and 232Th) and artificial (137Cs) radionuclides in the soil of the mountains of Maljen, Tara and Kopaonik in the Republic of Serbia over 2002-2015. In addition, the paper gives radiation hazard parameters, i.e., radium equivalent activity, absorbed dose rate, annual effective dose equivalent, external hazard index, annual gonadal dose equivalent, and excess lifetime cancer risk outdoors that we calculated from the obtained content of the natural radionuclides in the soil samples. We compared the parameters to previously published results for different parts of the country and looked into the radioecological status of the investigated areas.

Uzorci zemljišta prikupljeni su u periodu od 2002. do 2015. godine na različitim nadmorskim visinama. Na osnovu sadržaja radionuklida u zemljištu odredili smo parametre radijacionog rizika: radijum ekvivalentnu aktivnost, jačinu doze, godišnju efektivnu dozu spoljašnjeg zračenja, indeks spoljašnjeg hazarda, godišnju gonadnu dozu i faktor rizika pojave kancera na području planinskih regiona Republike Srbije, i potom ih uporedili sa ranije objavljenim rezultatima za pojedine regione Republike Srbije.

AB  - Након измерене високе концентрације радона у три просторије у једној кући  почетком 2018. године, настављено је испитивање концентрације у свим годишњим добима, а број просторија је повећан на пет. Као што је очекивано, концентрација радона је у току летњих месеци била много мања него у зимском периоду, првенствено због сталног проветравања. У осталим годишњим добима уочена је велико повећање коцентрације радона са смањењем спољашње температуре. Такође је уочено смањење концентрације радона у свим просто-ријама наредне зиме, за приближно исти хладни период, када је уместо угља коришћен дрвени пелет.
AB  - The high radon concentrations were measured in three rooms in one house at the beginning of 2018. After that, radon testing was continued during all seasons and the number of rooms was increased to five. As expected, the concentration of radon during the summer was much lower than in the winter period, primarily due to constant natural ventilation. In other seasons, a large increase in radon concentration with a decrease in the  outside  temperature  was  observed.  There  was  also  a  decrease  in  radon concentrations in all rooms in the following winter, in approximately the same cold period, when wood pellets were used instead of coal.

AB  - Berilijum-7 (7Be)je radioaktivni berilijumov izotop koji nastaje u interakcijama kosmič-kog zračenja sa atomima atmosfere. Intenzitet kosmičkog zračenja usled nehomogenosti magnetnog polja Zemlje, ispoljava prostornu distribuciju, dok je vremenska distribucija posledica vremenski promenljivog magnetnog polja Sunca. Cilj ovog istraţivanja je da se  izvrši  analiza  uticaja  vremenske  promene  intenziteta  kosmičkog  zračenja  na koncentraciju7Be  u  kompozitnim  mesečnim  uzorcima  ukupnog  (suvog  i  mokrog) depozita. Uzorci depozita su sakupljani u Institutu za nuklearne nauke "Vinča", a sva merenja  koncentracije 7Be su uraĎena u Laboratoriji za zaštitu od zračenja i zaštitu ţivotne sredine. Rezultati merenja uzoraka prikupljenih u periodu od 1994. do 2016. su korelirani sa mesečnim podacima o intenzitetu kosmičkog zračenja iz istog perioda, preuzetim  sa  sajta  stanice "Apatity", Polarnog geofizičkog instituta, Ruske akademije nauka.  Ova  stanica  poseduje  neutronski  monitor  "Standard  18-NM-64"  lociran  na nadmorskoj  visini  od  181  m  sa  geografskim  koordinatama  od  N:67,57°  i  E:33,39°. TakoĎe, rezultati merenja oba posmatrana parametra su grupisani po godinama i mese-cima u godini, a zatim su odreĎeni njihovi godišnji i mesečni indeksi. Nakon toga, za ispitane  parametre  su  meĎusobno  korelirani  kako  godišnji,  tako  i  njihovi  mesečni indeksi. Dobijeni rezultati ukazuju da fluktuacije kosmičkog zračenja utiču samo na varijacije  godišnjih  indeksa  koncentracije7Be   u   ukupnom   depozitu.   Koeficijent determinacije godišnjih indeksa posmatranih parametara govori da se modulisanošću kosmičkog zračenja moţe objasniti 33% varijacije godišnjih vrednosti koncentracije 7Be u depozitu.
AB  - Beryllium-7 (7Be) is a radioactive beryllium isotope that is produced in the interaction of cosmic radiation with atmospheric atoms. Due to the heterogenous of the Earth's magnetic  field,  the  intensity  of  cosmic  radiation  exhibits  spatial  distribution,  while  the time  distribution  is  a  consequence  of  the  time-varying  magnetic  field  of  the  Sun.  The aim  of thisresearch  is  to  analyzethe  influence  of  the  intensity  of  cosmic  radiation  on the 7Be concentration in samples of the total (dry and wet) deposit. The deposit samples were  collected  at  the  Vinţa  Institute  of  Nuclear  Sciences,  and  all 7Be  concentration measurements  were  performedin  the  Department  of  Radiation  and  Environmental Protection.  The  results  of  the  measurements  were  collected  in  the  period  from  1994  to 2016 and they were correlated with the monthly neutron monitor data of the "Apatity",the Polar Geophysical Institute, the Russian Academy of Sciences. This station has the neutron  monitor  "Standard  18-NM-64"  located  at  the  altitude  of  181  m  with  geogra-phical coordinates of N:  67.57° and E: 33.39°. Also, the results of the measurement of both  observed  parameters  are  grouped  by  years  and  months  of  the  year,  and  then  their annual and monthly indices were determined. After that, the annual as well as monthly indices  of  the  observed  parameters  were  correlated.  The  obtained  results  indicate  that the fluctuations in the galactic part of cosmic radiation affect the variation of the annual 7Be  concentration  index  in  the  deposit.  The  coefficient  of  determining  the  annual indices  of  the  observed  parameters  shows  that  the  modulation  of  cosmic  radiation  can explain  33%  of  the  variation of  the  annual  values of the concentration of 7Be in the deposit.

The  following  radiological parameters are presented in this study: soil-crop transfer factor, nuber of strontium units, discrimination  coefficient  and K-parameter.  These  parameters  are  calculated  based  on the specific activity of 90Sr and total Ca concentration in soil and crop. The results of the parameter calculation indicated that for the most part, 90Sr is acumulated in the root of the  crop,  which  confirmes  that  the  main  path  of  the  acumulation  is  the  resuspension from  soil; 90Sr  acumulation  rate,  in  comparison  to  total  Ca  in  soil,  depends  on  the  soil and crop type as well as the total Ca concentration in soil.

AB  - In 2018, Laboratory for Environment and Radiation Protection took part in the proficiency test "REM 2018 radon-in-water proficiency test". The task of this proficiency test was to determine the concentration of radon in the water sample. This sample  was  measured  by  gamma  spectrometry  on  HPGe  detector.  Firstly,  the measurement was performed on the native sample, without opening the bottle in which the sample was delivered. After that, the sample was placed into Marinelli beaker and measured again on the same detector. To calculate the activity concentration of radon in the  sample,  the  calibration  was  performed  using QA/QC  sample  from  the IAEA-TEL-2018-03 proficiency test andthe efficiency transfer was performed using EFFTRAN software. Comparison of the obtained results with the reference value, provided in the preliminary report of the proficiency test, showed that there is a significant influence of the measurement geometry and the calculation approach. In thispaper, the results of both approaches to the measurement and calculation will be presented and the trueness and precision of the results will be analyzed and commented.

AB  - The uncertainty of the measurement results is an indicator of the quality of the performed measurement. In the testing laboratories, the combined measurement uncertainty is usually given at the level of confidence of 95% (k = 2). If the laboratory analysis is preceded by a sampling procedure, the uncertainty budget of the measurement results should (according to ISO17025: 2017) include the uncertainty arising from the sampling procedure. This paper describes the procedure for estimating the uncertainty of the results of measurement due to sampling.

In the testing laboratories, the combined measurement uncertainty is usually given at the level of confidence of 95% (k = 2). If the laboratory analysis is preceded by a sampling procedure, the uncertainty budget of the measurement results should (according to ISO17025: 2017) include the uncertainty arising from the sampling procedure. This paper describes the procedure for estimating the uncertainty of the results of measurement due to sampling.",

In the spring and autumn season, leaves were collected in the area of normal background radiation levels represented by city parks in a multi-year period (2002-2012). Measurements by means of gamma-ray spectrometry showed 226Ra and 210Pb seasonal accumulation in leaves, while 238U and 235U could be detected only in autumn. Difference between seasons was not found significant for 40K and 137Cs. The study of radionuclides transfer factors was conducted by analyzing its relationships with basic soil properties at the beginning and the end of the vegetation period. © 2019, Editura Academiei Romane.

AB  - One of the main problems in quantitative gamma-ray spectroscopy is the determination of detection efficiency, for different energies, source-detector geometries, and composition of samples or sources. There are, in principle, three approaches to this issue: experimental, numerical, and semiempirical. Semiempirical approach is based on the calculation of the efficiency for the measured sample on the basis of an experimental efficiency measured on the same detector, but with a calibration source that can be of different size, geometry, density, or composition—the so-called efficiency transfer. The aim of this paper is to analyze the semiempirical approach, using EFFTRAN and MEFFTRAN software as a typical example. These software were used in the Department of Radiation and Environmental Protection, Vinča Institute of Nuclear Sciences, on three HPGe detectors. The results were compared to the experimentally obtained efficiency, and further validation is performed by measuring reference materials issued within the framework of several interlaboratory intercomparisons. The analysis of the results showed that the efficiency transfer produces good results with the discrepancies within the limits of the measurement uncertainty. Also, for intercomparison measurement, u test criterion for the trueness of the result was applied showing that the majority of the obtained results were acceptable. Some difficulties were identified, and the ways to overcome them were discussed.

AB  - Traces of particulate radioactive iodine (I-131) were detected in the European atmosphere in January/February 2017. Concentrations of this nuclear fission product were very low, ranging 0.1 to 10 mu Bq m(-3) except at one location in western Russia where they reached up to several mBq m(-3). Detections have been reported continuously over an 8-week period by about 30 monitoring stations. We examine possible emission source apportionments and rank them considering their expected contribution in terms of orders of magnitude from typical routine releases: radiopharmaceutical production units > sewage sludge incinerators > nuclear power plants > spontaneous fission of uranium in soil. Inverse modeling simulations indicate that the widespread detections of I-131 resulted from the combination of multiple source releases. Among them, those from radiopharmaceutical production units remain the most likely. One of them is located in Western Russia and its estimated source term complies with authorized limits. Other existing sources related to I-131 use (medical purposes or sewage sludge incineration) can explain detections on a rather local scale. As an enhancing factor, the prevailing wintertime meteorological situations marked by strong temperature inversions led to poor dispersion conditions that resulted in higher concentrations exceeding usual detection limits in use within the informal Ring of Five (Ro5) monitoring network.

AB  - Kaolins are used in a multiplicity of industries because of unique physical and chemical properties. Relationships between thermal and radioactivity properties are discussed in its application as a building material. Super-fine kaolin powder with particle sizes about 30 mu m was analyzed. Simultaneous TGA/DTA analysis was performed on powder samples at various heating rates in an argon atmosphere. Based on investigated thermal properties, it was concluded that dehydroxylation process can vary depending on the characteristics of starting material. The maximum degree of the dehydroxylation (D (T)) was obtained at the lowest rate of heating (D (T) = 60.79% for 10 A degrees C min(-1)). With an increase in the heating rate, decline in D (T) value was observed. Based on comprehensive testing, it was identified that the degree of dehydroxylation does not drop below 50%. It was concluded that appointed experimental conditions seem sufficient admissible for obtaining degree of dehydroxylation (D (T)) higher than 50%. In order to safe use of kaolin as a building material from the standpoint of radiological safety, content of natural radionuclides was determined by gamma spectrometry.

abstract = "Kaolins are used in a multiplicity of industries because of unique physical and chemical properties. Relationships between thermal and radioactivity properties are discussed in its application as a building material. Super-fine kaolin powder with particle sizes about 30 mu m was analyzed. Simultaneous TGA/DTA analysis was performed on powder samples at various heating rates in an argon atmosphere. Based on investigated thermal properties, it was concluded that dehydroxylation process can vary depending on the characteristics of starting material. The maximum degree of the dehydroxylation (D (T)) was obtained at the lowest rate of heating (D (T) = 60.79% for 10 A degrees C min(-1)). With an increase in the heating rate, decline in D (T) value was observed. Based on comprehensive testing, it was identified that the degree of dehydroxylation does not drop below 50%. It was concluded that appointed experimental conditions seem sufficient admissible for obtaining degree of dehydroxylation (D (T)) higher than 50%. In order to safe use of kaolin as a building material from the standpoint of radiological safety, content of natural radionuclides was determined by gamma spectrometry.",

AB  - Human activities may lead to increased levels of naturally occurring radioactive material and heavy metals in waters relative to undisturbed natural environment, consequently to reduced safety of environment. Therefore, evaluation of water quality from coal-fired power plants is essential to both environmental protection and protection of the human health. In this paper the concentrations of metals (K, Sr, and Pb) and corresponding radionuclides (K-40, Sr-90, and Pb-210) for 22 water samples in the vicinity of five coal-fired power plants in Serbia were determined. The total metal concentrations were measured using an atomic absorption spectrometer. The activities of radionuclides K-40 and Pb-210 were determined by gamma spectrometry using HPGe detector, while the activity of Sr-90 was determined by radiochemical analytical method and measured using low-level gas proportional counter. The water pollution status was assessed by the prospective method that is defined in this study. The preliminary results indicated that operation of the coal-fired power plants has no significant impact on the surrounding environment with regard to the radiological characteristics and content of metals of the investigated waters that can be used for suitable in future applications.

AB  - This study of environmental radioactivity was carried out in the soils of an urban area. Naturally occurring gamma-emitting radionuclides and man-made137Cs were found in the soil profiles collected from four parks in the central Belgrade city area and the soil layer was examined every 10 cm and to a depth of 50 cm. Radioisotope activity concentrations (Bq kg−1) in the samples of urban soil using the gamma-ray spectrometry method were in the range of 14–46 for238U, 33–50 for226Ra, 29–63 for210Pb, 1.2–3.4 for235U, 28–50 for232Th, 424–576 for40K and 0.7–35.8 for137Cs. Some of the basic physicochemical soil properties (pH, organic matter content, calcium-carbonate content, particle size distribution) were determined to investigate the impact on the vertical distribution of radionuclides. The results of this investigation showed that variations of activity concentration ratios of radionuclides that belong to the same (238U/226Ra) or different radioactive series (232Th/226Ra;235U/238U), including210Pb/137Cs ratios could well be explained by the properties of the soil. Alkaline pH reaction, the accumulation of organic matter in the uppermost and of carbonates in the deepest layers of urban soil had an effect on238U/226Ra, and210Pb/137Cs activity concentration ratio values, while232Th/226Ra and partially235U/238U ratios were associated with the particle sizes vertical distribution. A study of radionuclides in the samples of leaves of two deciduous tree species common for these parks was also conducted and210Pb and40K were found concentrated in leaves rather than other investigated radionuclides.

AB  - Soil represents a potential source of contamination of biota. Hence, tracking
distribution of radioactivity in the soil is very important, particularly in cultivated soil
used for intensive agricultural production, where it gives an insight into the cumulative
deposition and dispersion of radioactivity in that part of agroecosystems. To determine
the radioactivity of cultivated soil of southeast Belgrade, specific activities of natural
radionuclides 210Pb, 238U, 235U, 226Ra, 232Th and 40K were measured using high
resolution gamma spectrometry. This paper gives the vertical distribution of the
investigated radionuclides in the soil and a correlation of their specific activities with
the physico-chemical characteristics of the soil. The measured specific activities are
41-74 Bq kg-1 for 210Pb, 39-67 Bq kg-1 for 238U, 2,4-3,6 Bq kg-1 for 235U, 37-53 Bq kg-1
for 226Ra, 51-60 Bq kg-1 for 232Th and 540-670 Bq kg-1 for 40K. Pierson’s linear
correlation coefficients imply an association between the specific activities of 235U,
238U, 232Th and 40K and the physical and chemical soil characteristics in the
investigated area. The distribution of these radionuclides depends mostly on the content
of fine fraction - clay, but also on the content of humus, CaCO3 and organic carbon in
the soil. Our analysis shows no correlation between the specific activities of 210Pb and
226Ra and physico-chemical characteristics of the investigated soil samples.
