Radionuklidų pernašos iš dirvožemio į pušį (pinus silvestris l.) koeficientų tyrimas

Abstract

Radionuclides affect the environment and all its elements. The ligneous plant is one of these elements. Wood and other segments of tree accumulate the radionuclides. Radionuclides transfer factors from soil to the tree is use for estimate the accumulation of radionuclides in tree. In this article is analyzed the investigation and the experimental data of radionuclides transfer factors from soil to the pine (Pinus silvestris L.) wood. We investigate the transfer factors from soil layer 0- 25 cm to the tree of these radionuclides: Cs, 226Rn, Th aW"'K. Transfer factor from soil to the tree of'}7Cs vary from 0,001 ±0,0003 to 0,061 ±0,0016 m2/kg. Transfer factor from soil to the tree of2269A vary from 0,002 ± 0,0005 to 0.128 ± 0.030 m2/kg. Transfer factor from soil to the tree of 2}2Th vary from 0,005 ± 0.001 to 0.281 ± 0,095 m2/kg. Transfer factor from soil to the tree of4nK vary from 0.001 ± 0.0001 to 0.353 ±0.035 m2/kg.
