BS ISO 7503-1:2016和ISO 8769针对负责确定 固体表面存在放射性。ISO 7503分三部分发布，可联合使用或 根据需要分开。ISO 7503的本部分涉及通过直接和间接方法评估表面污染 相关仪器的测量和校准。本标准适用于α、β和光子发射器，并适用于医院， 大学、警察或工业机构。该标准也可用于评估 卡车、集装箱、包裹、设备上的活动，适用于任何处理 放射性物质。通常，它适用于定义明确的平面，其中使用了直接方法 然而，它也适用于不平坦的表面和进行间接擦拭试验的表面 这样比较合适。这些调查可在集装箱、无法进入的区域、非平坦区域进行 可使用擦拭测试的区域。ISO 7503的这一部分可能在紧急情况下有用， i、 e.涉及健康物理专业人员的核事故。ISO 7503的本部分不适用于皮肤、衣服和皮肤污染的评估 松散的材料，如砾石。注:使用擦拭试样评估放射性表面污染的试验方法如下: 在ISO 7503-2中处理。ISO 7503-3规定了放射性表面污染评估仪器的校准。交叉引用:ISO 8769ISO 11929ISO/IEC 17025ISO 31-0ISO 31-9ISO 11932ISO 18589-2ISO/IEC指南98-3ISO/IEC指南99IEC 60325IEC 60846-1购买本文件时提供的所有现行修订版均包含在购买本文件中。

BS ISO 7503-1:2016 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.This part of ISO 7503 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, nonflat 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.This part of ISO 7503 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.Cross References:ISO 8769ISO 11929ISO/IEC 17025ISO 31-0ISO 31-9ISO 11932ISO 18589-2ISO/IEC Guide 98-3ISO/IEC Guide 99IEC 60325IEC 60846-1All current amendments available at time of purchase are included with the purchase of this document.
