Radiation protection instrument Neutral dose equivalent (rate) meter1 ScopeThis standard applies to instruments that measure the ambient dose equivalent (rate) produced by neutron radiation below 20 MeV, which includes at least. a) a detection device, such as a device consisting of a thermal neutron detector and a neutron moderating and absorbing medium surrounding the detector; b) measuring device with display measurement, which can be integrated with the detection device or can be separated by cable connection Device. This standard includes instruments with energy ranges up to 20 MeV. If the instrument also provides an indication of the neutron dose, it should be satisfied with this standard. The neutron dose requirement. This standard does not specify test methods for instrument performance requirements in pulsed radiation fields. It is not certain whether the device designed to meet this standard is suitable Used for pulsed radiation fields. This standard specifies the performance requirements of the dose equivalent (rate) meter around the neutron and the test side to determine its performance to meet the requirements of this standard. law. This standard specifies the general characteristics, general test methods, radiation characteristics, electrical characteristics, mechanical characteristics of the dose equivalent (rate) meter around the neutron. Sex, safety and environmental characteristics, and the requirements of the certificate of conformity (see 13.2), and the neutron peripheral with alarm function Requirements and test methods for volume equivalents. Note. The response of the dose equivalent (rate) meter around the neutron is related to energy and may deviate significantly from the consistency requirement. However, the response in the actual neutron field is not Deviations from the same energy range tend to cancel each other out, so the response to the actual neutron field tends to be close to uniform. EJ/T.20086.1-2014 and ISO 12789-2 specify a range of broad spectrum neutron sources suitable for testing such instruments. For example. in the known spectrum When the environment is tested, the simulation work field specified in EJ/T.20086.1-2014 and ISO 12789-2 can be determined by the manufacturer and the user.
