适用范围: This part of IEC 60951 provides general guidance on the design principles and performance criteria for equipment for continuous high range area gamma monitoring in nuclear power plants for accident and post-accident conditions. General requirements for technical characteristics@ test procedures@ radiation characteristics@ electrical@ mechanical@ and environmental characteristics are given in IEC 60951-1. These requirements are applicable in this part unless otherwise stated. This standard is applicable to installed dose rate meters that are used to monitor high levels of gamma radiation during and after an accident. It covers equipment intended to isotropically measure air kerma@ ambient dose or other exposure quantities due to gamma radiation of energy between 80 keV and 7 MeV. The equipment is intended primarily for the purpose of nuclear plant safety. Portable instruments for emergency purposes and installed area radiation monitors used to determine continuously the radiological situation in working areas during normal operation are within the scope of IEC 60532
