摘要：

The paper presents results on determination of Sr-90 in bilberry and cowberry leaves (Vaccinium myrtillus and Vaccinium vitis-idaea) and the use of these plants as bio-monitors of radiostrontium contamination in Poland. Radiostrontium was determined by mean of liquid scintillation spectrometry preceded by radiochemical separation using Sr-resin and Sr-85 tracer. The approximate map of Sr-90 contamination of Poland is presented. The activity ratio between Sr-90 and obtained earlier data for Cs-137 in the same samples is discussed. The enhancement of radiostrontium content observed in northeastern Poland seems to be the trace of hot-particles fallout from initial Chernobyl cloud, which passed over Polish territory toward Scandinavia.
