Radiation Exposure of Occupationally Exposed Professionals in the Area - Medical

The aim of this study was to determine which medical professionals are subjected to greater exposure to ionizing radiation. To do a retrospective analysis of the results of individual dosimeters, thirty users from different medical specialties, sent by the Bolivian Institute of Nuclear Science and Technology for a period of 30 months. The specialities from state hospital included the services of Nuclear Medicine, X-ray, CT and where you have the service of Interventional Cardiology. Comparison was made of radiation exposures among different services. The review of readings of the dosimeters indicated that the highest exposure dose corresponding to two medical professionals of interventional cardiology with doses of 43.7 mSv and 23.1 mSv, respectively, compared to 11.2 mSv and and 29,4 4 mSv of the technicians who accompany the intervention procedures. In terms of radiation exposures of the workers occupationally exposed in nuclear medicine, the dose received by the technologist - 8 mSv, is higher as compared to that of nuclear physician - 3.2 mSv. It is observed that larger exposures to ionizing radiation in the hospital under investigation corresponds to the occupationally exposed professionals who spend more time with the patient, i.e., medical interventional cardiologist and medical technologist nuclear.
