Sponsor's own description

The objective of this study is to review the results of annual radiation doses received by interventional cardiologists and radiologists in France. The results of this study will allow the improvement of classification of interventional cardiology and radiology activities and procedures to help define radiation dose constraints for occupational exposure, according to the number and types of procedures performed.

The study is based on the hypothesis that some specialties in interventional cardiology (cardiology or rythmology procedures) and in interventional radiology (vascular, neuroradiology, osteoarticular) and some types of procedures present greater exposure risks for interventional cardiologists and radiologists. It is expected that the annual radiation dose limits for workers can be exceeded if good practices for both patient and worker radiation protection are not applied. Also, dosimetry equipment used to detect radiation dose although provided to the workers are not systematically worn by the physician during the procedure . The study is likely to show that for an equivalent speciality and number of procedures per type of act, the correct use of collective and personal radiation protection equipment (préciser) will lower occupational radiation exposure of physician . Similarly, for an equivalent activity and number of procedures per type of act , a trained physician would have a lower occupational exposure than an untrained physician. The physician's radiation exposure should therefore increase with a greater number of procedures per type of procedure performed and as the radiation dose delivered to the patient increase. Finally, there would be a different correlation between patient's radiation dose and physician's exposure depending on specialty, procedures, modality, experience and availability and use of collective and personal radiation protection equipment.
