摘　　要：目的检验参比单位土壤中^(90)Sr的分析能力,以提高各单位的检测水平和测量数据准确度。方法组织全国辐射环境监测实验室开展土壤中^(90)Sr的分析能力比对。结果参加本次比对有20个实验室,比对结果可以接受的占80%,不可以接受的占20%。结论比对整体结果良好。但土壤中^(90)Sr的分析仍存在一些问题,需要进一步研究。Objective To test the capability of soil ^90Sr analysis, and to improve the measuring level and data accuracy for each laboratory. Methods Organize an intercomparison experiment of soil ^90Sr analysis among the nationwide radiation environmem monitoring laboratories. Results Twenty laboratories participated in the intercomparison, the results of 80% laboratories are acceptable, while 20% are unacceptable. Conclusion The overall result was fine. Problems found in the intercomparison need future research.
