TY - JOUR TI - Uptake of naturally occurring radioisotopes by vegetation in a region of high radioactivity AB - The accumulation of four naturally occurring radionuclides of the sup(238)U series, uranium, sup(226)Ra, sup(210)Pb and sup(210)Po, in 15 species of native plants was investigated. Of the plants sampled some accumulated, but none concentrated uranium or sup(226)Ra. Grouseberry (Vaccinium scoparium Leiberg) appeared to concentrate sup(210)Pb and sup(210)Po. There were marked seasonal variations in the accumulation of uranium by grass (Calamagrostis rubescens Buckl.), and of sup(210)Pb and sup(210)Po by grass and fireweed (Epilobium angustifolium L.). High positive correlations between soil and vegetation radionuclide content were found for uranium in fireweed and grouseberry in spring, sup(226)Ra in willow (Salix scouleriana L.) in spring, and uranium in fireweed in summer.
