Interventional cardiologists (ICs) are repeatedly exposed to scattered ionising radiationduring the cardiac procedures they perform, and radiation protection is an important issuefor these medical professionals. The use of radiation protection tools is particularlyrelevant to this population. SISERI (Système d’Information de la Surveillance del’Exposition aux Rayonnement Ionisants, that is, an information system for monitoringexposure to ionising radiation) is a register that stores personal dosimeter readings fordosimetric monitoring. This paper, based on data for a sample of French ICs from theO’CLOC epidemiological study, aims to provide an overview of the use of radiationprotection equipment and dosimetric devices reported by ICs in a specific questionnaire aswell as the dosimetric information found in the SISERI database for this population.Material and Methods − Annual information on interventional cardiology activity for theperiod from 01/01/2005 to 31/12/2009 was collected in an occupational questionnaire. ICswere asked to report the frequency in which they used individual dosimeter and radiationprotection tools (lead apron, thyroid shield, eyewear or face shield, ceiling-suspendedshield) as follows: never (0% of the time), occasionally (<50%), regularly (>50%), always (100%). We retrieved theirmedical radiation exposure information (monitored status and monthly effective doses) fromthe SISERI database for the period 2005−2009. Results – Information for 132 ICs (mean age in2005 = 46 ± 7 years) wasavailable. All ICs reported routine use of lead aprons, in contrast to their occasionaluse of lead eyewear or face shields. During the study period, 49% reported systematic useof personal dosimeters, and 21% more regular use. On the other hand, 18% never used adosimeter during this period. The SISTERI database included 92% of our population, 73% ofwhom had complete annual dose monitoring in SISERI (corresponding to at least 11 monthsper year of recorded data). Conclusion − ICs must improve their regular use ofradiation protection tools and systematic use of personal dosimeters. The SISERI databaseis an appropriate tool for flagging those medical professionals exposed to ionisingradiation. Better awareness of the importance of radiation protection rules in thispopulation, in particular, systematic dosimeter use, remains an important issue.
