BS IEC 61322:2020 PDF

Scope: What is BS IEC 61322 about? BS IEC 61322 discusses radiation protection instrumentation. BS IEC 61322 applies to installed dose equivalent rate meters, warning assemblies and monitors. BS IEC 61322 covers equipment intended to measure neutron radiation in dose equivalent rates in the energy region between thermal and 20 MeV for the purposes of radiation protection. The assemblies considered in BS IEC 61322 comprise at least a detector assembly, which may, for example, consist of a detector probe (for thermal neutrons such as BF3 proportional counter, 3He proportional counter, 6LiI(Tl) scintillation detector, etc.), and a moderating and absorbing medium surrounding the detector. These assemblies also need to comprise of at least a processing assembly, which may be fitted into a centralized panel, which, in the case of warning assemblies and monitors provide signal outputs and contacts capable of activating an alarm or other trip circuits. Alternatively, the case when all the processing electronics are p...
