【摘要】 本文报道了1988—1989年我院参加世界卫生组织国际放射性参考中心（WHO IRC）组织的矿泉水中放射性分析比对的结果。参加这次分析比对的有14个国家的25个实验室,要求分析的核素包括天然铀、²³⁴U、²³⁵U、²³⁸U、²²⁶Ra 和²¹⁰Po,其放射性浓度在0.001—0.2 Bq/L 之间。有22个实验室向IRC 报告了分析结果,完成全部测定的实验室有5个（包括 IRC 和我院）。分析比对结果表明,我院的各项分析值与 IRC 参考值或各实验室的平均值比较接近。更多还原

【Abstract】 An intercomparison of the analysis of mineral water was organized by World HcalthOrganization,International Reference Center for Radioactivity（WHO IRC）in 1988.China Institutcfor Radiation Protection（CIRP）and other 24 laboratories from 14 countries participated this intercomparison.The items for comparison included the contents of natural uranium,²³⁴U,²³⁵U,²³⁸U,²²⁶Ra and ²¹⁰Po.Radioactivity levels of above radionuclides lay in the range 0.001 to 0.2 Bq/L.22laboratories reported their results.Only 5 laboratories,including IRC and CIRP completed alldetermination items required.The values reported by CIRP lay close to the IRC reference values ormean values.更多还原
