摘　　要：采用二-(2-乙基已基)磷酸萃取技术中锶-90的快速法和放置法,对2021年IAEA组织的实验室能力验证锶-90水样进行分析测量。测量结果满足准确度和精密度的IAEA评价标准,取得最终评价结果为A的良好成绩。通过测量结果相对偏差、Z值评价的比较与探讨,本次水样锶-90放射性分析中放置法优于快速法。Using the Sr-90 fast-method and place-method of HDEHP-kel-F,we analyzed and measured the Sr-90 radioac⁃tivity in water samples for IAEA Proficiency Test 2021.The measurement results met the IAEA evaluation criteria of accura⁃cy and precision,and the final evaluation result was A.By comparing and discussing the relative bias of the measured re⁃sults and Z-score,the place-method is superior to the fast-method in the analysis of Sr-90 radioactivity in water samples.
