本标准及其附录规定了对工厂钚监测至关重要的辐射防护仪器的性能标准。这里也描述了钚辐射。本标准中建立的性能标准仅限于能够测量（1）0.010至1.25 MeV能量范围内的光子辐射，（2）热至10 MeV能量范围内的中子辐射，以及（3）4.5至7.5 MeV发射能量范围内的α辐射的仪器。本标准不适用于特定仪器的构造，也未规定进行每次测量时使用的仪器，通用术语除外。本标准未定义生物测定项目所需的人员剂量计、废水监测系统或仪器的规范，也未定义监测紧急情况可能需要的要求。 在这些标准中，有两个动词被用来表示特定标准的严格程度。应表示必须满足的最低标准，而应表示建议作为良好实践的标准，并在可行时应用。

Performance criteria for radiation protection instrumentation essential to inplant plutonium monitoring is defined in this standard and its appendix. Plutonium radiations are also characterized here. Performance criteria established in this standard are limited to instruments capable of measuring (1) photon radiations within the energy range of 0.010 to 1.25 MeV, (2) neutron radiations within the energy range from thermal to 10 MeV, and (3) alpha radiations within the emitted energy range of 4.5 to 7.5 MeV. This standard does not apply to the construction of specific instruments nor does it specify instrumentation to be employed for each survey to be conducted, other than in generic terms. This standard does not define specifications for personnel dosimeters, effluent monitoring systems, or instruments needed in bioassay programs, nor does this standard define those requirements which may be needed to monitor emergency conditions. Throughout these criteria, two verbs have been used to indicate the degree of rigor intended by the specific criterion. Shall indicates a minimum criterion that must be met, while should indicates a criterion that is recommended as good practice and is to be applied when practical.
