 note = {Rapid analysis for Sr-90, Th-232, and U-238 in human urine samples collected in a radiation emergency can be developed by co-precipitation with calcium phosphate and separation using a Sr-resin (Eichrom Technologies, Inc.) column. The nuclides were measured by inductively coupled plasma mass spectrometry (ICP-MS) or a low background beta-counter. Spike tests yielded a good recovery of above 90%. Fractions of Sr-90 and the other nuclides (Th-232 and U-238) were separated in about 2 hours. It was judged that the developed method would be an effective bioassay method in radiation emergency.},
