 note = {Rapid measurement of radioactivity from 89,90Sr in aqueous solutions is performed using a technique combining a strontium rad disk and a picobeta spectrometer. Identification of 89,90sr radionuclides is accomplished in as little as 90min in a radiation-tainted solution that contains more highly radioactive cesium. It is possible to perform triage by assessing skin exposure doses in this short time. This simple technique could be used in mobile laboratories. 89,90Sr having 1 Bq radioactivities are measured in 10 kBq 137Cs in aqueous solution. The radioactivity contained in rinse water used to decontaminate the feet of workers who stepped into highly contaminated water in the basement of the turbine building of Unit 3 at the Fukushima Daiichi nuclear power station was measured. The amount of 90Sr radioactivity in rinse water using the authors'rapid measurement technique (0.29Bq mL-1)and a traditional method agree well, with 3.6% difference. Based on this agreement, this technique is confirmed to be useful for rapid measurement of 89,90Sr radioactivities.},
