核能.核燃料技术.测定核电厂产生的低和中级放射性废物包放射性的换算因子法

[中文适用范围]： 本国际标准为凭经验确定比例因子以评估低和中水平放射性废物包中难以测量的核素的放射性的通用基本方法提供了指导。 本国际标准为表征水冷反应堆核电厂产生的污染废物所使用的比例因子提供了通用指南。 本国际标准也适用于其他反应堆类型，例如气冷反应堆。 本国际标准不涵盖基于理论考虑（即不基于实验测量）确定比例因子的方法。 [外文原描述]： ISO 21238:2007 gives guidelines for the common basic methodology of empirically determining scaling factors to evaluate the radioactivity of difficult-to-measure nuclides in low- and intermediate-level radioactive waste packages. ISO 21238:2007 gives common guidelines for the scaling factors used in the characterization of contaminated wastes produced in nuclear power plants with water-cooled reactor. ISO 21238:2007 is also relevant to other reactor types, such as gas-cooled reactors. Methodologies for determining scaling factors based on theoretical considerations (i.e. not based on experimental measurement) are not covered by ISO 21238:2007.
