ISO 7503（所有部分）和ISO 8769针对负责测定固体表面放射性的人员。ISO 7503分三部分发布，可根据需要联合或单独使用。 ISO 7503-1:2016涉及通过直接和间接测量评估表面污染，以及相关仪器的校准。 本标准适用于α、β和光子发射器，适用于医院、大学、警察或工业机构。该标准还可用于评估卡车、集装箱、包裹、设备上的活动，适用于任何处理放射性材料的组织。一般来说，它适用于定义明确的平面，其中直接方法适用，但也可用于非平面的表面，以及间接擦拭试验适用的表面。这些调查可能会在集装箱、无法进入的区域、非集装箱上进行- 可以进行擦拭测试的平坦区域。ISO 7503的这一部分可能在紧急情况下有用，即在涉及健康物理专业人员的核事故中。 ISO 7503-1:2016不适用于皮肤、衣物和松散材料（如砾石）污染的评估。 注:ISO 7503-2规定了使用擦拭试样评估放射性表面污染的试验方法。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 determining the radioactivity present on solid surfaces. ISO 7503 is published in three parts and can be used jointly or separately according to needs. ISO 7503-1:2016 relates to the assessment of surface contamination by direct and indirect measurements and the calibration of the associated instrumentation. The standard applies to alpha-, beta- and photon emitters and is intended for use by hospitals, universities, police, or industrial establishments. The standard also can be used in the assessment of activity on trucks, containers, parcels, equipment and is applicable in any organization which handles radioactive materials. Generally, it is applicable to well defined flat surfaces where direct methods are applicable, however, it can also be used for surfaces which are not flat and where indirect wipe tests would be appropriate. These investigations may be carried out on containers, inaccessible areas, non-flat areas where wipe tests can be used. This part of ISO 7503 may be useful in emergency situations, i.e. in nuclear accidents where health physics professionals would be involved. ISO 7503-1:2016 does not apply to the evaluation of contamination of the skin, of clothing and of loose material such as gravel. NOTE The test method using wipe-test samples for the evaluation of radioactive surface contaminations is dealt with in ISO 7503-2. The calibration of instruments for the evaluation of radioactive surface contaminations is dealt with in ISO 7503-3.
