BS ISO 7503-3:2016针对负责测定放射性的人员 存在于固体表面。ISO 7503的本部分适用于根据 单位面积由直接和间接测量方法确定，并处理 仪器校准。ISO 7503的本部分适用于定义明确的表面，例如设备和设施的表面， 放射性材料容器、密封源、建筑物或土地。ISO 7503的这一部分可用于实验室和设备/安装控制以及修复 以及监控活动以符合发布标准。ISO 7503的本部分还涉及以下方面:处理复杂排放放射性核素的校准实验室或机构 无参考校准源的特性或放射性核素；面临评估表面污染任务的机构包括 放射性核素混合物；控制核材料运输或材料/设备清关的机构/当局 根据国家立法指导值或国际公约限制。ISO 7503的本部分不适用于皮肤、衣物或松散材料的污染，例如 沙砾注:直接评估阿尔法发射器、贝塔发射器和光子发射器的表面污染 在ISO 7503-1中处理。放射性表面评估用擦拭试样的试验方法 ISO 7503-2对污染物进行了处理。交叉引用:ISO 7503-1ISO 7503-2ISO 8769ISO 11929ISO/IEC 17025IEC 60325NUREG- 1575:2000IAEA SSR-6:2012IAEA 72:2012ISO 11932ISO 80000-1ISO 80000-10ISO/IEC指南98-3GUM:1995ISO/IEC指南99购买本文件时提供的所有当前修订版均包含在购买本文件中。

BS ISO 7503-3:2016 are addressed to the people responsible for determining the radioactivity present on solid surfaces.This part of ISO 7503 applies to the evaluation of contamination on surfaces in terms of activity per unit area by direct and indirect methods of measurement and deals with the complex aspects of instrument calibration.This part of ISO 7503 is applicable to well-defined surfaces, such as those of equipment and facilities, containers of radioactive materials, sealed sources, and buildings or land.This part of ISO 7503 can be used for laboratory and equipment/installation control and for remediation and monitoring activities to comply with release criteria.This part of ISO 7503 also refers to the following:calibration laboratories or institutions dealing with radionuclides with complex emission characteristics or radionuclides for which no reference calibration sources are available;institutions confronted with the task to evaluate surface contaminations consisting of a radionuclide mixture;institutions/authorities controlling nuclear material transports or material/equipment clearance according to national legislation guideline values or international convention limits.This part of ISO 7503 does not apply to contamination of the skin, clothing, or loose material, such as gravel.NOTE Direct evaluation of surface contamination from alpha-emitters, beta-emitters and photon emitters is dealt with in ISO 7503-1. The test method using wipe-test samples for the evaluation of radioactive surface contaminations is dealt with in ISO 7503-2.Cross References:ISO 7503-1ISO 7503-2ISO 8769ISO 11929ISO/IEC 17025IEC 60325NUREG-1575:2000IAEA SSR-6:2012IAEA 72:2012ISO 11932ISO 80000-1ISO 80000-10ISO/IEC Guide 98-3GUM:1995ISO/IEC Guide 99All current amendments available at time of purchase are included with the purchase of this document.
