Valentine* ConsultantScopePerformance 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.
