Journal of environmental radioactivity 2013 MarIn this work we have used moss Pleurozium schreberi as a bioindicator of radioactive materials in environment. The following radionuclides were determined in moss samples: (137)Cs, (40)K, (210)Pb, (212)Pb, (214)Pb, (214)Bi, (231)Th, (235)U and (228)Ac, but not all of them in each sample. The highest activity concentrations were found for naturally occurring (210)Pb, (40)K and the artificial isotope (137)Cs. Activities of radioisotopes were recalculated into mass concentrations and the statistical methods intended for constrained data processing were used. Analysis of our results showed at most a weak relationship between radioisotope mass concentrations in moss. It was supposed that concentrations of some elements depended on the same, currently unknown, factors. Copyright © 2012 Elsevier Ltd. All rights reserved.
