《GB/T 15053-2008使用辐射显色薄膜和聚甲基丙烯酸甲酯剂量测量系统测量吸收剂量的标准方法》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。
标准规定了使用辐射显色薄膜和聚甲基丙烯酸甲酯(PMMA)剂量测量系统测定吸收剂量的操作和测量程序。适用于这两种剂量测量系统测定光子或电子照射下用水吸收剂量表示被照材料中的吸收剂量。本标准代替GB/T 15053-1994《使用辐射显色薄膜和聚甲基丙烯酸甲酯剂量测量系统测量吸收剂量的标准方法》。
本标准与GB/T 15053-1994相比主要变化如下:
―――重新规定了剂量计使用时的辐射能量和辐照温度范围;
―――增加了“规范性引用文件”;
―――在“术语和定义中”增加了部分术语条款,并对原有的部分术语进行了重新定义;
―――将“仪器设备”章的标题改为“剂量测量系统”;
―――增加了“仪器设备性能检查”的技术内容;
―――对“剂量测量系统的校准”章内容作了大的调整,并增加了“被校准剂量计在辐射场中所占体积内剂量率的变化应在±1%以内(极差≤2%)”的要求;
―――增加了“批次剂量计特性描述”的技术内容;
―――增加了“剂量测量系统的应用”的技术内容;
―――用“测量不确定度”的章标题及相关的技术内容替代了1994版的“误差分析”技术内容;
Scope
This standard specifies the operation and measurement procedures for the determination of absorbed dose using radiochromic film and polymethylmethacrylate (PMMA) dosimetry systems. This standard applies to these two dosimetry systems to determine the absorbed dose of water under photon or electron irradiation to indicate the absorbed dose in the irradiated material. These two dosimetry systems are designated as work-level dosimetry systems (see GB/T 16640). 1.2 This standard specifies the applicable conditions of the two dose measurement systems as follows: 1.2.1 Radiochromic film dose measurement system a) Absorbed dose range: 1Gy~100kGy. b) Absorbed dose rate range: 1×10-2Gy.s-1~1×1013Gy.s-1 c) Radiation energy range: 0.1 MeV~50MeV (for photons); d) Irradiation temperature range: -78°C~-60°C 1.2.2 Polymethyl methacrylate (PMMA) dose measurement system a) Absorbed dose range: 0.1Gy~100kGy. b) Absorbed dose rate range: 1×10-2Gy.s-1~1×107Gy.s-1 c) Radiation energy range: 0.1 MeV~50MeV (for photons); 3MeV~50MeV (for electrons). d) Irradiation temperature range: -78°C~50°C 1.3 This standard does not involve safety issues related to use (if any). It is the responsibility of the user of the standard to establish applicable safety and health standards and to determine the applicable limitations prior to use.
