This document specifies the characteristics of reference measurement standards of radioactive surface contamination, traceable to national measurement standards, for the calibration of surface contamination monitors. This document relates to alpha-emitters, beta-emitters, and photon emitters of maximum photon energy not greater than 1,5 MeV.

ISO 8769:2020(E) Introduction Radioactive contamination of surfaces can result from spilling, splashing, or leakage from unsealed sources, or breakage or loss of integrity of sealed sources. It can lead to the spread of contamination, loss of quality control and can give rise to …

2020年6月22日 · 本文件规定了放射性表面污染参考测量标准的特性，可追溯到国家测量标准，用于表面污染监测器的校准。 本文件涉及最大光子能量不大于1.5 MeV的α发射器、β发射器和光子发射器。 它没有描述使用这些参考测量标准校准表面污染监测器所涉及的程序。 此类程序在IEC 60325 [6]、IEC 62363 [7]和其他文件中有规定。 注意，由于所提出的光子标准中的一些包括滤波器，光子标准被视为特定能量范围的光子的参考测量标准，而不是特定放射性核素的参考测量 …
