标准范围

ISO/ASTM 51261涵盖了选择和校准用于测量伽马射线或X射线场以及用于辐射处理的电子束中吸收剂量的剂量测定系统的基础。它讨论了在校准过程中或作为产品商业辐射加工质量保证的一部分在常规基础上可能使用的剂量学系统的类型。ISO/ASTM 51261还讨论了吸收剂量的解释，并简要概述了与剂量测定相关的不确定度的测量。分析仪器的校准细节在个人剂量测定系统标准实践中进行了说明。吸收剂量范围高达1mGy（100mrad）。涵盖的源能量为0.1至50 MeV的光子和电子。本国际标准应与其他标准中涵盖的特定剂量测定系统和应用的标准实践和指南一起使用。它不包括中子或重带电粒子辐射处理的剂量测定。

ISO/ASTM 51261 covers the basis for selecting and calibrating dosimetry systems used to measure absorbed doses in gamma-ray or X-ray fields and in electron beams used for radiation processing. It discusses the types of dosimetry systems that may be used during calibration or on a routine basis as part of quality assurance in commercial radiation processing of products. ISO/ASTM 51261 also discusses interpretation of absorbed doses and briefly outlines measurements of the uncertainties associated with the dosimetry. The details of the calibration of the analytical instrumentation are addressed in individual dosimetry system standard practices.The absorbed-dose range covered is up to 1 MGy (100 Mrad). Source energies covered are from 0,1 to 50 MeV photons and electrons.This International Standard should be used along with standard practices and guides for specific dosimetry systems and applications covered in other standards. It does not cover dosimetry for radiation processing with neutrons or heavy charged particles.
