Separation and determination of 90Sr in urine with HDEHP levextrel resin
Description
A method for the rapid determination of 90Sr in urine is described. After the urine sample is concentrated by carbonate coprecipitation, the 90Y is separated with HDEHP levextrel resin. Then, it is precipitated as Y2(C2O4)3 for measurement of its β-activity. According to the β-counts, the amount of 90Sr in the urine can be calculated. The method is simple and rapid. The separation of Sr, Ca, Mg is satisfactory; the decontamination for fission product elements is good. The recovery of radiochemical Y is consistent with its chemical recovery, about 90%. The detection limit of the method is 7.5 x 10-2 Bq/l
