Scope

GB/T 7164-2022 (Characteristics and test methods of radiation detectors for nuclear reactors) is available as an English-translated PDF.

GB/T 7164-2022 is the Chinese standard "Characteristics and test methods of radiation detectors for nuclear reactors". Its scope clause reads: This document specifies the characteristics and test methods for radiation detectors used in nuclear reactors.

The radiation detectors used in nuclear reactors described in this document are all gas ionizing radiation detectors, and their working medium is gas.

This document applies to the neutron proportional counter tubes (BF3 counter tube, 3He counter tube, boron-coated counter tube) used in the nuclear testing system outside the nuclear reactor several tubes), fission ionization chamber (working in pulse mode, working in mean square voltage mode, working in current mode), boron-coated ionization chamber (including gamma) Compensated ionization chamber, non-compensated boron-coated ionization chamber), also suitable for mobile micro fission ionization chamber used in nuclear reactor core measurement system.

Similar detectors in other applications can be used for reference. Its clauses include terms and definitions.
