ISO 7503（所有部分）和ISO 8769针对负责测量固体表面放射性的人员。 ISO 7503-2:2016适用于通过间接测量方法，根据单位面积的活动性对表面污染进行评估。 ISO 7503-2:2016适用于定义明确的表面，如设备和设施、放射性材料容器、密封源和建筑物或土地的表面。 ISO 7503-2:2016可用于实验室和设备/安装控制以及修复和监测活动，以符合释放标准。 ISO 7503-2:2016也指根据国家立法指导值或国际公约限制控制核材料运输或材料/设备清关的机构/当局。 ISO 7503-2:2016不适用于皮肤、衣物或松散材料（如砾石）的污染。 注:ISO 7503-1对阿尔法发射器、贝塔发射器和光子发射器的表面污染进行了直接评估。ISO 7503-3规定了放射性表面污染评估仪器的校准。

ISO 7503 (all parts) and ISO 8769 are addressed to the people responsible for measuring the radioactivity present on solid surfaces. ISO 7503-2:2016 applies to the evaluation of contamination on surfaces in terms of activity per unit area by an indirect method of measurement. ISO 7503-2:2016 is applicable to well-defined surfaces, such as those of equipment and facilities, containers of radioactive materials, sealed sources and buildings or land. ISO 7503-2:2016 can be used for laboratory and equipment/installation control and for remediation and monitoring activities to comply with release criteria. ISO 7503-2:2016 also refers to institutions/authorities controlling nuclear material transports or material/equipment clearance according to national legislation guideline values or international convention limits. ISO 7503-2:2016 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 calibration of instruments for the evaluation of radioactive surface contaminations is dealt with in ISO 7503-3.
