Photon dosimeters are almost universally used in all radiation practices, from personal and ambient monitoring to environmental monitoring, emergency response and protection of workers and the public to protect people from harmful effects of ionising radiation. These dosimeters are tested and calibrated according to ISO 4037 standards. In 2019, all 4 parts of ISO 4037 standards series were updated, with many changes introduced.
The aim of this project is to provide a reliable metrological framework for:
- the establishment of harmonised procedures for traceable x-ray spectrometry which are now absent,
- the generation of new data for the ISO 4037 standards regarding Am-241 reference fields,
- the development of cost-effective procedures and guidance for the calibration of dosimeters, to enable smaller metrology institutes and other calibration laboratories to implement the ISO 4037:2019 standard series, as well as to provide training to emerging metrology institutes,
- the production of guidance on validated procedures for harmonised type testing based on IEC standards (e.g., IEC 61526, IEC 60846-1, IEC 60846-2, IEC 61017, IEC 60532 and IEC 62387) for the commonly used radiation protection dosimeters with valid metrological solutions,
- the assessment of future standardisation needs related to new and upcoming technologies and the creation of a guidance document for the implementation of the new operational quantities of ICRU Report 95 into standards and regulations and to disseminate this to policymakers, manufacturers, regulators, metrology networks, standardisation bodies and laboratories
