本文件的主要目的是提供建立电子顺磁共振波谱回顾剂量测定程序所需的最低可接受标准，并报告结果。 第二个目的是便于比较不同实验室获得的与吸收剂量估算相关的测量结果。 本文件涵盖测量材料中吸收剂量的测定。它不包括器官或身体剂量的计算。它涵盖了生物和无生命样本的测量，特别是: a） 基于玻璃、塑料、服装面料、糖类等无生命环境材料。 ，通常在X波段微波频率（8GHz至12GHz）下制造； b） 体外牙釉质:在样本管中使用浓缩牙釉质，通常使用X波段频率，但也考虑使用更高的频率； c） 体内牙齿剂量学，目前使用L波段（1 GHz至2 GHz），但也在考虑更高的频率； d） 体外指甲剂量学使用指甲剪，主要在X波段测量，但也考虑了更高的频率； e） 在完整手指或脚趾的X波段进行活体指甲剂量测定； f） 骨的体外测量，通常采用X波段频率，但也考虑更高的频率。 对于生物样品，在将其从人或动物身上移除后，在实验室条件下对样品进行体外测量，而在活体内进行测量时，无需移除样品，并可在现场条件下进行。 注:本文件中提到的剂量是被测材料中电离辐射的吸收剂量。

The primary purpose of this document is to provide minimum acceptable criteria required to establish a procedure for retrospective dosimetry by electron paramagnetic resonance spectroscopy and to report the results. The second purpose is to facilitate the comparison of measurements related to absorbed dose estimation obtained in different laboratories. This document covers the determination of absorbed dose in the measured material. It does not cover the calculation of dose to organs or to the body. It covers measurements in both biological and inanimate samples, and specifically: a) based on inanimate environmental materials like glass, plastics, clothing fabrics, saccharides, etc., usually made at X-band microwave frequencies (8 GHz to 12 GHz); b) in vitro tooth enamel using concentrated enamel in a sample tube, usually employing X-band frequency, but higher frequencies are also being considered; c) in vivo tooth dosimetry, currently using L-band (1 GHz to 2 GHz), but higher frequencies are also being considered; d) in vitro nail dosimetry using nail clippings measured principally at X-band, but higher frequencies are also being considered; e) in vivo nail dosimetry with the measurements made at X-band on the intact finger or toe; f) in vitro measurements of bone, usually employing X-band frequency, but higher frequencies are also being considered. For biological samples, in vitro measurements are carried out in samples after their removal from the person or animal and under laboratory conditions, whereas the measurements in vivo are carried out without sample removal and may take place under field conditions. NOTE The dose referred to in this document is the absorbed dose of ionizing radiation in the measured materials.
