标准摘要
[中文适用范围]： 本文件提供了在使用剂量测定系统的工作场所验证剂量测定系统的方法和标准。 本文件中的标准适用于不符合 ISO 21909-1 中描述的能量和方向相关响应标准的剂量测定系统。 工作场所剂量测定系统的鉴定旨在证明： ——剂量测定系统不符合 ISO 21909-1 中定义的能量或方向相关响应的某些要求不会导致剂量测定系统的显着差异。 确定特定工作场所的剂量； ——或者，用于该特定研究工作场所的校正因子或函数使剂量测定系统能够准确确定常规剂量值，其不确定性类似于 ISO 21909-1 中给出的不确定性。 注：本文件针对所有相关利益相关者：IMS、认可或监管机构以及特定剂量测定的用户（用户是指将剂量测定系统分配给辐射工作人员并记录分配的剂量的实体。 ）附件 A 中给出了表征工作场所场的方法，以便对剂量测定系统进行鉴定。 附件 B 是补充性的，因为一旦选择了一种方法，它就给出了要遵循的实用方法。 剂量测定系统的提供者应提供符合ISO 21909-1的型式试验结果。 然而，当待认证的剂量测定系统不符合ISO 21909-1处理响应的能量和角度相关性的所有标准时，ISO 21909-1的某些测试就不能进行。 ISO 21909-1 和 ISO 21909-2 之间的联系在附件 E 中描述。 本文件仅涉及中子个人监测，而不涉及临界事故情况。 [外文原描述]： This document provides methodology and criteria to qualify the dosimetry system at workplaces where it is used. The criteria in this document apply to dosimetry systems which do not meet the criteria with regard to energy and direction dependent responses described in ISO 21909-1. The qualification of the dosimetry system at workplace aims to demonstrate that: — either, the non-conformity of the dosimetry system to some of the requirements on the energy or direction dependent responses defined in ISO 21909-1 does not lead to significant discrepancies in the dose determination for a certain workplace field; — or, that the correction factor or function used for this specific studied workplace enables the dosimetry system to accurately determine the conventional dose value with uncertainties similar to the ones given in ISO 21909-1. NOTE This document is directed at all stakeholders who are involved: IMSs, accreditation or regulatory bodies, and users of the particular dosimetry (the user is meant as the entity which assigns the dosimetry system to the radiation worker and records the assigned dose.) The methodologies to characterize the work place field in order to perform the qualification of the dosimetry system are given in Annex A. Annex B is complementary as it gives the practical methods to follow, once one methodology is chosen. The provider of the dosimetry system shall provide the type test results corresponding to ISO 21909‑1. However, when the dosimetry system to be qualified does not comply with all the criteria of ISO 21909‑1 dealing with the energy and angle dependence of the response, some tests of the ISO 21909-1 can be not performed. The links between ISO 21909-1 and ISO 21909-2 are described in Annex E. This document only addresses neutron personal monitoring and not criticality accident conditions.
