The number of diagnostic and interventional medical procedures using ionising radiations is rising steadily, and procedures resulting in higher patient and staff doses are being performed more frequently. As such, the need for education and training of medical staff (including medical students) and other healthcare professionals in the principles of radiation protection is even more compelling than in the past. The Commission has made basic recommendations for such education and training of these individuals in ICRP Publications 103 and 105 (ICRP, 2007a,b). The present publication expands considerably on these basic recommendations with regard to various categories of medical practitioners and other healthcare professionals who perform or provide support for diagnostic and interventional procedures utilising ionising radiation and nuclear medicine therapy.
