摘要
Abstract
Focused on the environmental soil sample contaminated by spent fuel,a Pm sepa-ration procedure was established with a recovery greater than 70% for Pm and the decontam-ination factor greater than 10 3 for the interference elements.The activity of 1 47 Pm standard sample was determined by liquid scintillation counting (LSC)with the efficiency tracing method (ETM),giving a relative deviation less than 0.5%.The analysis method of 1 47 Pm was validated for simulated polluted soil sample (prepared by mixing the spent fuel with environmental soil)and the results are in good agreement with the referenced data with a relative deviation of 2%.关键词
