Scope

This standard applies to instruments used to measure the ambient dose equivalent (rate) generated by neutron radiation with an energy of less than 20 MeV, which includes at least the following:
a) Detection devices, such as devices composed of thermal neutron detectors and neutron moderation and absorption media around the detectors;
b) Measurement devices with displays of measurement values, which can be integrated with the detection devices or be separate devices connected by cables.
This standard includes instruments with an energy range up to 20 MeV. If the instruments also provide an indication of neutron doses, they should meet the neutron dose requirements specified in this standard.
This standard does not specify test methods for the performance requirements of instruments in pulsed radiation fields. It cannot be determined whether devices designed to meet this standard are suitable for use in pulsed radiation fields.
This standard specifies the performance requirements for neutron ambient dose equivalent (rate) instruments and the test methods for determining whether their performance meets the requirements of this standard. It specifies the general characteristics, general test methods, radiation characteristics, electrical characteristics, mechanical characteristics, safety characteristics, and environmental characteristics of neutron ambient dose equivalent (rate) instruments, and gives the requirements for qualification certificates (see 13.2). It also specifies the requirements and test methods for neutron ambient dose equivalent (rate) instruments with alarm functions.
Note: The response of neutron ambient dose equivalent (rate) instruments is energy-dependent and may deviate significantly from the consistency requirements. However, in actual neutron fields, the response deviations due to different energy ranges tend to cancel each other out, so the response to actual neutron fields is often close to consistent.
