Overview

This International Standard is applicable to assemblies designed to measure the ambient dose equivalent (rate) due to neutron radiation in fields that contain neutrons with energies below 20 MeV, and which comprise at least: a) a detection assembly, which may, for example, consist of a detector probe for thermal neutrons and an arrangement of neutron moderating and absorbing media surrounding the detector; b) a measuring assembly with a display for the measured quantity, which may be incorporated into a single assembly with the detector or connected to it by means of a flexible cable. Instruments with energy range up to 1 GeV are covered by this standard. If the instrument also provides indication of the neutron dose, it should meet the neutron dose requirements stated in this standard. No test methods are given in this standard regarding the requirements for performance characteristics of the devices in pulsed radiation fields. It should therefore be noted that a device may be unsuitable for use in such fields even though it complies with this standard. ISO 12789 specifies a list of suitable neutron radiation sources that have broad spectra suitable for testing such dose (power) meters. The responsible committee is DKE/GK 852 "Strahlenschutzdosimeter" ("Radiation protection devices") of the DKE (German Commission for Electrical, Electronic and Information Technologies) at DIN and VDE.
