土壤和水中放射性核素实验室间测量比对

Abstract

Abstract: Inter-comparison among analytical laboratories for measurements of radionuclides in soil and water samples is described in this article. Inter-comparison media included spiked soil, real soil, and spiked water. Determination of ⁹⁰Sr, ⁶⁰Co, ¹³⁴Cs, and ¹³⁷Cs for spiked soil, ²³⁸U, ²³²Th, ²²⁶Ra, ⁴⁰K, ⁹⁰Sr, and ¹³⁷Cs for real soil, and ³H, ⁹⁰Sr, ⁶⁰Co, ¹³⁴Cs, and ¹³⁷Cs for spiked water were carried out. Eleven laboratories participated in this inter-comparison, and the result of inter-comparison was fine. Key problems found during the inter-comparison are summarized and some suggestions are put forward for future inter-comparison activities.

Key words: laboratory of environment monitoring, soil, water, radioactivity, inter-comparison
