标准摘要
[中文适用范围]: 本文件的主要目的是提供建立电子顺磁共振波谱回顾性剂量测定程序并报告结果所需的最低可接受标准。 第二个目的是促进不同实验室获得的吸收剂量估算相关测量结果的比较。 本文件涵盖了被测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品的测量,特别是: a) 基于无生命环境材料,如玻璃、塑料、服装面料、糖类等,通常在 X 波段微波频率(8 GHz 至 12 GHz)下进行; b) 体外牙釉质使用样品管中浓缩的牙釉质,通常采用 X 波段频率,但也正在考虑更高的频率; c) 体内牙齿剂量测定,目前使用 L 频段(1 GHz 至 2 GHz),但也在考虑更高的频率; d) 主要在 X 波段测量使用指甲剪的体外指甲剂量测定,但也正在考虑更高的频率; e) 体内指甲剂量测定,在完整手指或脚趾的 X 波段进行测量; f) 体外骨骼测量,通常采用 X 波段频率,但也正在考虑更高的频率。 对于生物样品,体外测量是在实验室条件下从人或动物身上取出样品后进行的,而体内测量是在不取出样品的情况下进行的,并且可以在现场条件下进行。 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。 [外文原描述]: 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.
