GB/T 16841-2008 in English

《GB/T 16841-2008能量为 300 keV～25 MeV 电子束辐射加工装置剂量学导则》由TC58（全国核能标准化技术委员会）归口，TC58SC4（全国核能标准化技术委员会放射性同位素分会）执行，主管部门为国家标准化管理委员会。
标准规定了电子束辐射加工中为保证全部产品接受到产生预期辐射效应所需的剂量，在安装确认、运行确认、性能确认（IQ、OQ和PQ）和日常加工中所涉及的剂量测量程序，以及有关可能影响这些过程和用以监控产品中吸收剂量的其他程序。本标准代替GB/T 16841-1997《能量为300keV～25 MeV电子束辐射加工装置剂量学导则》。本
标准与GB/T 16841-1997相比主要变化如下：
―――重新规定了标准的适用“范围”；
―――增加了部分术语，并对原标准的部分术语进行了重新定义；
―――增加了“剂量计系统的校准”条和具体的要求；
―――用“安装确认”、“运行确认”、“性能确认”和“日常生产加工”替代了“装置确认”、“加工确认”和
“日常生产加工”；
―――增加了“加工参数”章和相关内容；
―――增加了不确定度的分类标准和评定准则；
―――细化了用深度剂量分布方法确定电子束初始能量的方法和条件；
―――重新描述了“微波功率加速器”和“射频功率型加速器”的性能特征。

Scope

1.1 This standard specifies the dose measurement involved in installation confirmation, operation confirmation, performance confirmation (IQ, OQ and PQ) and daily processing in order to ensure that all products receive the dose required to produce the expected radiation effect in electron beam radiation processing procedures, and other procedures that may affect these processes and are used to monitor absorbed doses in products. 1.2 The energy range of electron beams applicable to this standard: 300keV～25MeV. 1.3 Dose measurement is only one part of the total quality management of irradiation processing. In special applications such as radiation sterilization of medical and health care products and food preservation, other measurements are required in addition to dosimetry. 1.4 ISO and ASTM have published specific standards applicable to food irradiation and healthcare products. See ISO/ASTM 51431 for specific standards for food irradiation, and GB 18280 for specific standards for radiation sterilization of medical and healthcare products. In use, the provisions of GB 18280 take precedence over the provisions of other standards. 1.5 This standard does not address safety issues related to use. The user of this standard is responsible for establishing applicable safety and health standards and determining applicable limitations prior to use.
