IEC 62387:2020 is available as IEC 62387:2020 RLV which contains the International Standard and its Redline version, showing all changes of the technical content compared to the previous edition.
IEC 62387:2020 applies to all kinds of passive dosimetry systems that are used for measuring:
- the personal dose equivalent Hp(10) (for individual whole body monitoring),
- the personal dose equivalent Hp(3) (for individual eye lens monitoring),
- the personal dose equivalent Hp(0,07) (for both individual whole body skin and local skin for extremity monitoring),
- the ambient dose equivalent H*(10) (for workplace and environmental monitoring),
- the directional dose equivalent H'(3) (for workplace and environmental monitoring), or
- the directional dose equivalent H'(0,07) (for workplace and environmental monitoring).
This document applies to dosimetry systems that measure external photon and/or beta radiation in the dose range between 0,01 mSv and 10 Sv and in the energy ranges given in Table 1. All the energy values are mean energies with respect to the fluence. The dosimetry systems usually use electronic devices for the data evaluation and thus are often computer controlled.

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.

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

Radiation protection instrumentation - Installed radiation portal monitors (RPMs) for the detection of illicit trafficking of radioactive and nuclear materials

IEC 62244:2019 defines the performance requirements of installed monitors used for the detection of gamma and neutron radiation emitters. These monitors are commonly known as radiation portal monitors or RPMs. They are used to monitor vehicles, cargo containers, people, or packages and are typically located at national and international border crossings. They may be used at any location where there is a need for this type of monitoring. This document establishes the general, radiological, climatic, mechanical, electric and electromagnetic and documentation requirements and associated test methods. This document does not apply to the performance of spectroscopy-based portal monitors covered in IEC 62484. This second edition cancels and replaces the first edition issued in 2006. This edition includes the following significant technical changes with respect to the previous edition:
a) making the standard consistent with the new standards for detection of illicit trafficking of radioactive material (see the Introduction);
b) creating unformed functionality test for all environmental, electromagnetic and mechanical tests and a requirement for the coefficient of variation of each nominal mean reading;
c) reference to IEC 62706 for the environmental, electromagnetic and mechanical test conditions;
d) adding information regarding climatic exposures.

Radiation protection instrumentation - Measuring the imaging performance of X-ray computed tomography (CT) security-screening systems

IEC 62945:2018 provides test methods for the evaluation of image quality of computed tomography (CT) security-screening systems. The quality of data for automated analysis is the primary concern. Security screening systems are generally used to scan parcels, including luggage, for the presence of illicit items such as explosives, drugs, or other contraband. Many of the screening systems currently used, particularly in transportation security applications, are based on CT imaging technology.
