137Cs ir 40K pernašos iš dirvos į pušį įvertinimas Ruklos - Gaižiūnų ir Kairių kariniuose poligonuose

Abstract

Artificial 137Cs and natural 40K radioisotopes are important to determine pollution with radioactive materials. There are two significant periods of 137 Cs contamination: experiments of nuclear weapon in 1945-1980 and accident of Chernobyl nuclear power station in 1986. Biggest part of articial radionuclide 137 Cs is accumulated in upper layer of soil. Radionuclides with nutritious matter are migrating from soil to tree. This article is about artificial 137 Cs and natural 40K radionuclides distribution in pine timber annual tree rings, and in the soil of pines habitats, influence of climate to distribution of radioisotopes 137 Cs and 40K from soil to pines in Rukla-Gaidžiūnai and Kairiai military grounds.
