针对气溶胶、沉降灰、土壤、生物及淡水等环境样品中90 Sr、239+240 Pu 的联合分析进行了流程设计，并通过实际样品的测量对流程进行了验证。结果表明：90 Sr 分析流程的化学回收率为44.3%~90.2%，平均值为73.8%；239+240 Pu 分析流程的放化回收率为40.2%~104.3%，平均值为79.3%。在可给出单个样品化学(放化)回收率的前提下，该联合分析流程可以满足日常环境监测的要求。

A procedure for joint analyses of 90 Sr and 23 9 +240 Pu in aerosol,fallout,soil,biolo-gy and freshwater samples is reported.The procedure is validated by application to real sam-ples.According to the measurement results,chemical recoveries of 90 Sr are in the range of 44.3%-90.2%,and the average is 73.8%;radiochemical recoveries of 23 9 +240 Pu 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.
