Examination of Radioactive Contamination in the Soil-Plant System and Their Transfer to Selected Animal Tissues

This paper investigates gamma emitter radioactivity in a system consisting of soil and plants. Some selected samples of tissues of animals fed with the plants from these sites were also measured. In soil and plant samples artificial (Cs, Cs) and natural (thorium and uranium series) isotopes were detected. Despite the relatively high content of the natural isotopes in plants and their seeds, their accumulation in animal tissues was not detected. The K isotope was transferred in the chain soil-plant-animal in the highest degree. From the group of the natural isotopes, only Pb was detected in examined animal tissue samples. Other natural isotopes were below detection level. In the samples heavy metal content was also examined. In any sample no clement concentration was noticed above trade acceptable limit.
