Catheterism in medical procedures is
responsible for high X-ray doses, both to patients and
medical staff. Aiming to reduce this dose, modern
fluoroscopy equipment have been developed using pulsed X
ray, but there is no agreement in the literature on the
efficacy of these devices in reducing the dose. This study
presents the results of measured occupational doses during
simulated medical procedures, generated both for pulsed
and continuous fluoroscopy, and the calculations allowing
to quantify the reduction resulting by the use of pulsed
technology. A mapping of radiation intensities was
performed in the Laboratory in order to suggest better
places (lower occupational  doses) for personnel during
medical procedures, and is presented as well.
