Radiation protection instrumentation - Installed ambient dose equivalent rate meters, warning and monitoring assemblies for neutrons with energies from thermal to 20 MeV

IEC 61322:2020 applies to installed dose equivalent rate meters, warning assemblies and monitors, as defined below. It 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.
Assemblies of this type are commonly defined as area radiation monitors. They are normally employed to determine continuously the radiological situation in working areas in which the radiation field may change with time, for example, nuclear power plants, particle accelerators, high-activity laboratories, fuel reprocessing plants, etc., and provide alarms when the radiation field goes outside predetermined limits.
The assemblies considered in this document 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;
a processing assembly, which may be fitted into a centralized panel, which, in the case of warning assemblies and monitors, provides signal outputs and contacts capable of activating alarm or other trip circuits;
alternatively, the case when all the processing electronics are placed within the detection unit (so called "smart blocks") may be considered. In this case the functions of the processing assembly will be composed of only the indication, the providing signal outputs and contacts.

IEC TS 63050:2019(Main)
Radiation protection instrumentation - Dosemeters for pulsed fields of ionizing radiation

IEC TS 63050:2019 applies to all types of dosemeters, irrespective of the type of radiation intended to be measured. Tests according to this document determine whether a single radiation pulse can be measured correctly even if the dosemeter is in the internal state relevant for measuring background or environmental radiation.
The annex in the document gives some parameter values for typical workplaces where pulsed radiation occurs.
This document considers the pulsation of the radiation field as an additional influence quantity like particle energy and direction of radiation incidence. Therefore, the tests described are additional to all the tests in the instrument specific standards. This document describes methods to determine the following characteristic parameters of the dosemeters:
the maximum measurable dose rate in the pulse, Hmeas,max
the maximum measurable dose in the pulse, Hmeas,max
the minimal pulse duration, tmeas,min and
the range for the pulse repetition frequency, fmeas,min  to fmeas,max
