Abstract

A sequential method has been developed for the estimation of106Ru,137Cs, and90Sr in urine using beta counting. After completely destroying the organic matter in urine,106Ru is oxidized to volatile ruthenium tetroxide and allowed to reactin-situ with polyethylene powder;137Cs is concentrated on ammonium phosphomolybdate and estimated as tetraphenylborate;90Sr is coprecipitated as strontium sulphate and converted to carbonate. The recoveries have been found to be better than 83% for all of the radionuclides. The minimum detection limits are 0.16, 0.85, and 0.14 Bq/dm3 for106Ru,137Cs, and90Sr, respectively. Yttrium-90 fraction of90Sr is also estimated using sodium nitroprusside as reagent, after allowing it to grow for 14 days.
