WG 8 - TC 45/SC 45B/WG 8

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.

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

IEC 60846-2:2015 applies to portable or transportable dose equivalent (rate) meters and/or monitors for the measurement of ambient and/or directional dose equivalent (rate) from external beta, X and gamma radiation for energies up to 10 MeV during emergency situations. The object of this International Standard is to specify the design requirements and the performance characteristics of dose equivalent (rate) meters intended for the determination of ambient and/or directional dose equivalent (rate) as defined in ICRU Report 47 under emergency conditions. The main technical change with regard to the previous edition consists of an update to the revised edition of IEC 60846-1:2009.
This publication is to be read in conjunction with IEC 60846-1:2009.

IEC 61005:2014 specifies requirements for the performance characteristics of neutron ambient dose equivalent (rate) meters, and prescribes the methods of testing in order to determine compliance with this standard. This standard specifies general characteristics, general test procedures, radiation characteristics, electrical, mechanical, safety and environmental characteristics, and also the identification certificate (see 13.2). Requirements and test procedures are also specified for the alarm performance of the neutron ambient dose equivalent (rate) meters, equipped with alarm provisions. This new edition includes the following significant technical changes with respect to the previous edition:
- upper neutron energy of the instruments covered by the standard is increased to 20 MeV;
- requirement for the variation of the relative response due to neutron energy is modified;
- a clause for additivity of the indicated value (neutron dose/dose rate) is introduced;
- environmental testing methods and requirements are referred to IEC 62706.

IEC/TS 62743:2012(E) applies to all types of counting dosemeters, irrespective of the measuring quantity and the type of radiation intended to be measured. It ensures that a single radiation pulse can be correctly measured even if the dosemeter is in the internal state relevant for measuring background or environmental radiation. The characteristics of the dosemeter for repeated pulses is expected to be better than for one single radiation pulse with the same parameters but worse than for continuous radiation, i.e., in between of the characteristics for these two extreme conditions. 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 respective standards.

IEC 61526:2010 specifies general characteristics, general test procedures, radiation characteristics as well as electrical, mechanical, safety and environmental characteristics. The only requirements specified for associated readout systems are those which affect its accuracy of readout of the personal dose equivalent and alarm settings and those which concern the influence of the reader on the dosemeter. This new edition includes the following significant technical changes with regard to the previous one:
- improved determination of constancy of the dose response and statistical fluctuations;
- abolition of classes of personal dose equivalent meters in relation to retention of stored information;
- inclusion of usage categories of personal dosemeters.

IEC 60846-1:2009 specifies the design requirements and the performance characteristics of dose equivalent (rate) meters intended for the determination of ambient dose equivalent (rate) and directional dose equivalent (rate) as defined in ICRU Report 47. Applies to dose equivalent (rate) meters and/or monitors for the measurement of ambient dose equivalent (rate) and/or directional dose equivalent (rate) from external beta, X and gamma radiation.
