Photon dosimeters are used for measuring radiation doses to protect people from the harmful effects of ionising radiation. However, the recent update of the basic standard for photon reference radiation fields in radiation protection, ISO 4037:2019, has presented significant challenges to calibration laboratories and industry, such as high costs and increased need for manpower. This project “Harmonisation, update and implementation of standards related to radiation protection dosimeters for photon radiation” (EURAMET 22NRM07) will provide protocols and guidance to calibration laboratories, metrology institutes, standardisation bodies and regulators for a harmonized approach to radiation protection measurements and calibrations. Proposals to update ISO 4037:2019 and future needs for type testing and possible implementation of new radiation protection quantities according to ICRU Report 95 will also be provided, leading to compatible procedures and requirements.
