[中文适用范围]： 使用擦拭测试样品确定表面污染的活性 [外文原描述]： 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.
