In 2023, there are still two areas for improvement, as in the preceding years. The first concerns the updating of personnel training in occupational radiation protection (in 59% of the departments inspected in 2023, all the staff concerned received their training less than three years ago), a requirement for which ASN notes a slight regression over the last three years. The second recurrent area for improvement is in the coordination of the prevention measures with outside contractors, even if a small improvement is noted in 2023, with slightly more than a third of the nuclear medicine departments having drawn up a prevention plan with all the outside contractors. 2.3.3.2 Radiation protection of nuclear medicine patients Since ASN resolution 2019-DC-0667 of 18 April 2019 on DRLs(8) came into effect, ASN has been assessing the new requirements 8. Order of 23 May 2019 approving ASN resolution 2019-DC-0667 of 18 April 2019 concerning the methods for evaluating ionising radiation doses delivered to patients during a radiology procedure, fluoroscopy-guided interventional or nuclear medicine practices, and the updating of the corresponding diagnostic reference levels. concerning the quality of collection of doses, their analysis and the optimisation put in place where necessary. The ASN inspectors note that the percentage of departments deploying a complete optimisation approach (see Graph 7 above) is relatively stable at 68%, with improvements required in the evaluation and analysis of the delivered doses and administered activities. Management of the third-party quality controls of the MDs remains satisfactory but ASN notes a regression in 2023, with 81% of the inspected departments having carried out the quality controls on all their MDs at the required regulatory frequency, compared with more than 95% in the preceding years (see Graph 7 above). The organisational measures in place to allow the involvement of a medical physicist, the identification of their duties and the recording of the time they are present on the site are slightly less GRAPH Development of nuclear medicine department compliance with patient radiation protection regulations (2019-2023) 7 Complete management of annual external quality controls Complete management of DRLs Organisation of medical physics 0% 10% 20% 30% 40% 50% 60% 70% 80% 90% 100% NB: no DRL regulations in 2019. 2023 2022 2021 2020 2019 GRAPH Development of nuclear medicine department compliance with occupational radiation protection regulations (2019-2023) 6 0% 10% 20% 30% 40% 50% 60% 70% 80% 90% 100% 2023 2022 2021 2020 2019 Coordination of protection measures Training of workers in radiation protection Defining of restricted areas Dosimetric monitoring of workers RPE-O with valid certificate 226 ASN Report on the state of nuclear safety and radiation protection in France in 2023 • 07 • Medical uses of ionising radiation
