辐射保护用基准辐射场.基本概念和定义

[中文适用范围]： 本国际标准定义了用于外部辐射（特别是β、中子和光子辐射）辐射防护剂量测定的剂量计和设备校准的术语和基本概念。 它定义了辐射防护剂量计和剂量率计的测量量，并给出了建立这些量的建议。 对于个人监测，它涵盖全身和四肢剂量计（包括皮肤和眼睛晶状体剂量计），对于区域监测，它涵盖便携式和安装式剂量计。 给出了用于参考辐射场中个体和区域监测的剂量计和剂量率计的校准指南。 针对个人剂量计使用的参考点和体模的位置提出了建议。 本国际标准还涉及确定辐射质量和辐射入射角函数的响应。 它旨在供校准实验室和制造商使用。 [外文原描述]： ISO 29661:2012 defines terms and fundamental concepts for the calibration of dosemeters and equipment used for the radiation protection dosimetry of external radiation -- in particular, for beta, neutron and photon radiation. It defines the measurement quantities for radiation protection dosemeters and doserate meters and gives recommendations for establishing these quantities. For individual monitoring, it covers whole body and extremity dosemeters (including those for the skin and the eye lens), and for area monitoring, portable and installed dosemeters. Guidelines are given for the calibration of dosemeters and doserate meters used for individual and area monitoring in reference radiation fields. Recommendations are made for the position of the reference point and the phantom to be used for personal dosemeters. ISO 29661:2012 also deals with the determination of the response as a function of radiation quality and angle of radiation incidence. ISO 29661:2012 is intended to be used by calibration laboratories and manufacturers.
