摘　　要：以 2 3 6Pu作产额示踪剂测定了 6 0 0多个土壤样品中 2 3 8Pu分析的全程化学产额 ,其产额值呈正态分布 ,最可几产额值为 0 .4 8,标准偏差为 0 .2 0。采用示踪法进行全程化学产额校正比用预定化学产额值 0 .The chemical yields of overall process for analyzing 238 Pu in more than 600 soil samples are determined by using 236 Pu as a yield tracer. The values of chemical yield appear normal distribution. The most probable yield value is 0.48, standard deviation is 0.20. Great errors will be engendered for radiochemical analysis of plutonium isotopes if corrections of measured results only based on predeterncined chemical yield obtained by tracing test as a fixed corrected factor of 0.70 and not using chemical yield obtained tracer as dynamic corrected factor.
