Abstract

Abstract

A procedure for joint analyses of ⁹⁰Sr and ^239+240Pu in aerosol, fallout, soil, biology and freshwater samples is reported. The procedure is validated by application to real samples. According to the measurement results, chemical recoveries of ⁹⁰Sr are in the range of 44.3%-90.2%, and the average is 73.8%; radiochemical recoveries of ^239+240Pu are in the range of 40.2%-104.3%, and the average is 79.3%. Under the premise that each sample has its own chemical (radiochemical) recovery, the procedure can satisfy the demand of the environmental monitoring.
