AB  - During the years 2001 and 2010, the content of U-238, Ra-226, in K-40 and Cs-137 in agricultural soil and soil geochemical characteristics were measured on 50 locations in Northern Province of Serbia - Vojvodina. The locations for sampling were selected so that they proportionately represent all geomorphologic units in the region. The content of clay and humus varied within wide limits depending on soil type and influence the activity concentrations of radionuclides. In this paper we analyzed correlations between radionuclides content and geochemical characteristics of the soil. Possible influence of fertilizers on U-238 content in soil was discussed. The main conclusion is that measured maximal activity concentrations for U-238 (87 Bq/kg), Ra-226 (44.7 Bq/kg), Th-232 (55.5 Bq/kg) and Cs-137 (29 Bq/kg) at 30 cm. depth could not endanger the safety of food production. The process of genesis of soil and cultivation mode plays a dominant role on the characteristics of the soil. The most significant correlation was found between the activity concentrations of K-40 and clay content in agricultural soil.

AB  - The most dominant source of indoor radon is the underlying soil, so the enhanced levels of radon are usually expected in mountain regions and geology units with high radium and uranium content in surface soils. Laboratory for radioactivity and dose measurement, Faculty of Sciences, University of Novi Sad has rich databases of natural radionuclides concentrations in Vojvodina soil and also of indoor radon concentrations for the region of Vojvodina, Northern Province of Serbia. In this paper we present the results of correlative and multivariate analysis of these results and soil characteristics in order to estimate the geogenic radon potential. The correlative and multivariate analysis were done using Toolkit for Multivariate Analysis software package TMVA package, within ROOT analysis framework, which uses several comparable multivariate methods for our analysis. The evaluation ranking results based on the best signal efficiency and purity, show that the Boosted Decision Trees (BDT) and Multi Layer Preceptor (MLP), based on Artificial Neural Network (ANN), are multivariate methods which give the best results in the analysis. The BDTG multivariate method shows that variables with the highest importance are radionuclides activity on 30 cm depth. Moreover, the multivariate regression methods give a good approximation of indoor radon activity using full set of input variables. On several locations in the city of Novi Sad the results of indoor radon concentrations, radon emanation from soil, gamma spectrometry measurements of underlying soil and geology characteristics of soil were analyzed in detail in order to verify previously obtained correlations for Vojvodina soil.

AB  - In 2002, the first year of the project titled "Soil characterization and land management for production of high-value food from wheat and corn", agricultural land was surveyed in two locations. The survey covered an area of about 500 ha which was used for wheat production (location Skorenovac) and sweet corn (location Srbobran). Both locations were found to fully comply with the criteria for production of high-value food, i.e., regarding water-physical and chemical soil properties and the contents of biogenous macro and microelements heavy metals and polycyclic aromatic hydrocarbons (PAHs). Generally, the analyzed samples showed no indication of increased radioactivity that could jeopardize food production. The measured concentrations of 137Cs, taking into consideration the transfer factors of that isotope into plants, should not endanger the safety of the produced food.

Istraživanjem je obuhvaćena površina zemljišta od oko 500 ha na kojem se proizvodila pšenica (lokalitet Skorenovac) i kukuruz šećerac (lokalitet Srbobran). Utvrđeno je da prema kriterijumima za proizvodnju visokovredne hrane, kvalitet zemljišta kada je reč o vodno-fizičkim i hemijskim svojstvima kao i u pogledu sadržaja biogenih (makro i mikroelemenata) i teških metala, na oba ispitivana lokaliteta u potpunosti odgovara. Zbog prisustva zagađivača u blizini lokaliteta Skorenovac (Železara Smederevo), trebalo bi uspostaviti monitoring praćenja stanja plodnosti i zagađenja zemljišta opasnim i štetnim elementima iz procesa proizvodnje gvozda. Na osnovu dobijenih vrednosti sadržaja i nivoa najmanjeg rizika ustanovljenog od strane američke agencije za zaštitu životne sredine (U.S. EPA 1993) može se reći da je ukupan prosečan sadržaj u ispitanom zemljištu iznad granice minimalnog rizika. Međutim imajući u vidu da su ovo u zemljištu, a da je njihovo usvajanje od strane biljaka u zavisnosti od koncentracije i veličine molekula, a takođe i da ne postoji čvrsta korelacija između nivoa u zemljištu i u biljkama gajenim na njemu, jer biljke takođe usvajaju ova jedinjenja i iz vazduha, može se zaključiti daje nivo u zemljištu takav da neće ugroziti proizvodnju zdravstveno bezbedne hrane. Sadržaj u ispitanom zemljištu kako ukupnih tako i pojedinih je daleko ispod gornje dozvoljene koncentracije prema kriterijumima koji se koriste u Poljskoj. U našoj zemlji je tek potreb no ustanoviti MDK za ova jedinjenja u zemljištu. Generalno se može zaključiti da uzorci zemljišta sa ispitivanil lokaliteta ne ukazuju na povećanje radioaktivnosti koje bi ugrozile proizvodnju hrane. Izmerene koncentracije aktivnosti 137Cs, uzimajući i obzir transfer faktore ovog izotopa u biljke, ne bi trebalo da ugroze zdravstvenu bezbednost proizvedene hrane.
