辐射防护.工业用Υ辐射照相设备.性能、设计和试验规范

[中文适用范围]： 本国际标准规定了第 4 条中定义的各种类别的便携式、移动式和固定式曝光容器的伽马射线照相设备的性能、设计和测试要求。 它适用于设计用于允许受控使用密封装置发射的伽马辐射的设备。 用于工业射线照相目的的放射源，以便在按照有关辐射防护的现行法规使用该设备时保护人员。 但需要强调的是，就设备和密封放射源的运输而言，遵守本国际标准并不能替代满足相关国际运输法规的要求（原子能机构放射性材料安全运输法规：IAEA- STI-PUB 998、安全标准系列第 ST-1 号和第 ST-2 号，和/或相关国家运输法规）。 本国际标准不涵盖工业伽马射线照相设备的操作使用。 本设备的用户应遵守国家法规和操作规范。 [外文原描述]： ISO 3999:2004 specifies the performance, design and test requirements of apparatus for gamma radiography with portable, mobile and fixed exposure containers of the various categories defined in Clause 4. It applies to apparatus designed to allow the controlled use of gamma radiation emitted by a sealed radioactive source for industrial radiography purposes, in order that persons will be safeguarded when the apparatus is used in conformity with the regulations in force regarding radiation protection. It is emphasised, however, that so far as transport of apparatus and sealed radioactive source is concerned, compliance with ISO 3999:2004 is no substitute for satisfying the requirements of relevant international transport regulations (IAEA Regulations for the safe transport of radioactive materials: IAEA-STI-PUB 998, Safety Standards Series ST-1 and ST-2, and/or the relevant national transport regulations). The operational use of apparatus for industrial gamma radiography is not covered by ISO 3999:2004. Users of this equipment shall comply with national regulations and codes of practice.
