Rapid radiochemical analysis of uranium and plutonium in emergency urine samples

AbstractA novel method for rapid radioanalytical measurement of uranium and plutonium in 100ml emergency urine samples was developed, through optimized selection of the separation and purification process and a combined measurement with ICP-TOF-MS and alpha spectrometry. The typical analytical time is within 6  h, the recovery rates are more than 80%, and the minimum detection activity concentrations are 3.4 × 10−4 Bq/L for238U and 2.5  × 10−3 Bq/L for239Pu respectively. The spiked test shows that this method can be used for quantitative evaluation of the activity concentration of238U and239Pu in urine samples accurately.
