摘要/Abstract

摘要： 介绍1997—2004年间中国辐射防护研究院分析测试中心参加的美国EML组织的检验环境放射性测量质量的一个项目,分析了3种介质的43个样品,本实验室共报出了212个数据。所报出数据的通过率为97%,3%未通过。未通过数据3种介质均有,涉及4个核素,分别为²⁴¹Am、⁶⁰Co、⁵⁷Co和⁵⁴Mn。通过实验室间比对,表明:(1)本实验室γ谱分析的效率刻度是相对准确的,未发现系统误差。(2)γ谱分析中低能核素被干扰问题仍需进一步解决。

Abstract: China Institute for Radiation Protection (CIRP) has participated in a quality assessment program organized by US EML for testing the quality of environmental radioactivity measurements from 1997 to 2004. A total number of 43 samples in three different matrices were analyzed, and 212 analytical results were presented. For the evaluation performance, 97% of the results were designated as A (Acceptable) and 3% as N (Not Acceptable). The N (Not Acceptable) results were found for four nuclides in all three sample matrices including ²⁴¹Am, ⁶⁰Co, ⁵⁷Co and ⁵⁴Mn. The evaluation results of this inter-comparison project showed that the efficiency calibration for γ spectrometry analysis at CIRP has been acceptable but the interferences on the low-energy radionuclides has not yet been treated very well.

Key words: environmental matrix, radionuclide measurement, interlaboratory comparison, evaluation criteriaofic
