Content of (226)Ra, (228)Ra and uranium isotopes in waters from subsurface aquifers was studied. The sampling points were chosen for having the elevated natural content of iron and manganese. Measurements of radium were made by LSC, while uranium was measured by alpha spectrometry. Waste sludge was measured by gamma spectrometry and three-stage BCR sequential extraction was performed. Radon activity concentration in the air at water treatment plants was determined and dose adsorbed by staff was calculated.
研究了地下含水层水中（226）镭、（228）镭和铀同位素的含量。选择采样点是因为其铁和锰的天然含量较高。镭的测量采用液体闪烁计数法，而铀则通过α能谱法测量。对废污泥进行了γ能谱分析，并进行了三步BCR连续萃取。测定了水处理厂空气中的氡活度浓度，并计算了工作人员的吸附剂量。
