Abstract
Approximately 100 freshwater samples were collected in Ukraine, Russia, and Belorussia with regard to the Chernobyl accident. Thorium and uranium were determined by both quantitative and semiquantitative analysis modes of inductively coupled plasma mass spectrometry (ICP-MS). Thorium-232 was detected in only a few samples. Uranium concentrations ranged from non-detectable to 1,000 ng/ml. Mean and median concentrations of [sup 238]U were found to be 30.7[+-]139 and 0.7 ng/ml, respectively. The isotope ratio of [sup 234]U/[sup 238]U ranged from 4,6 x 10[sup -5] to 4,4 x 10[sup -4]. Mean ratio of [sup 235]U/[sup 238]U was 0.00721[+-]0.00006 (n=27). (author) 17 refs.; 1 fig.; 5 tabs.
