Description
The radionuclides 222Rn and 220Rn are measured by incorporating their daughters 214Pb and 212Pb in a very thin layer of PbS and accumulating the alpha spectrum of their daughter products 214Po and 212Po. The median yield was measured as 88% using a known amount of 210Pb tracer. A single fumarole and all 23 geothermal wells tested were found to contain 220Rn. As isotopes of Th, Bi, Po and Ra, are also absorbed in the PbS layer, the method can be used for determinations of these in tap-water. (author). 28 refs., 8 figs., 1 tab
