Radionuclides from Chernobyl hot particles in the environment of North-Eastern Poland - A leaching experiment
The Henry Niewodniczanski Institute of Nuclear Physics, 31-342 Krakow, Poland
The north-eastern Poland is the area where fallout of Chernobyl "fuel-like hot-particles" occurred. Experiment on the leaching out of radionuclides from forest litter was performed. Five samples were subsequently leached out by : a weak hydrochloric acid (fulvic acid fraction), ammonia water (humic acid fraction) and 2 M HCl (soluble fraction). Residue was analysed as well, after full mineralisation. Results on total activities and its distribution between fractions obtained for : 137Cs, 90Sr, 239+240Pu, 238Pu and 241Am are presented. Relatively high activities of plutonium were observed in humic acid fractions. This founding support suggestions by other authors on possible complexing of Pu by humic acid.
