标准范围

本文件规定了γ辐射放射性核素的固体、液体或气源的特性，用作校准γ射线光谱仪的参考测量标准。这些参考测量标准可追溯至国家测量标准。本文件不描述使用这些参考测量标准校准γ射线光谱仪所涉及的程序。ISO？中规定了这些程序20042和其他文件。本文件规定了伽马校准的推荐参考辐射-射线光谱仪。本文件涵盖但不限于发射能量范围为60？的光子的伽马发射器千伏到1836？千伏。这些参考辐射是以点源或根据可追溯到国家标准的活动规定的充分扩展源的形式实现的。实验室拟用于制备扩展标准的液体标准也在本文件范围内。根据ISO？生产的标准物质（RM）17034超出了本文件的范围。

This document specifies the characteristics of solid, liquid or gas sources of gamma emitting radionuclides used as reference measurement standards for the calibration of gamma-ray spectrometers. These reference measurement standards are traceable to national measurement standards.This document does not describe the procedures involved in the use of these reference measurement standards for the calibration of gamma-ray spectrometers. Such procedures are specified in ISO 20042 and other documents.This document specifies recommended reference radiations for the calibration of gamma-ray spectrometers. This document covers, but is not restricted to, gamma emitters which emit photons in the energy range of 60 keV to 1 836 keV. These reference radiations are realized in the form of point sources or adequately extended sources specified in terms of activity which are traceable to national standards.Liquid standards that are intended to be used for preparing extended standards by the laboratories are also within the scope of this document. Reference materials (RMs) produced in accordance with ISO 17034 are out of scope of this document.
