This study evaluates the distribution of the dose received by work-people involved in portable digital veterinary radiology procedures and checks the dose reduction obtained with the use of individual protection equipments. For this evaluation measurements were made using TLD-100 thermoluminescent dosimeters,positioned at seven different spots on the body of the assistants: hands, chest (outside the apron), thyroid (inside the apron), left and right eye corners and at the forehead, and in five different spots in the veterinarian: chest (outside the apron), thyroid (inside the apron), left and right eye corners and the center of the eyes. The dosage was evaluated through the 63 procedures performed with 49 assistants and a veterinarian in the metropolitan region of Curitiba, PR. The results show the importance of using thyroid protection and lead aprons to reduce the dosage received by the veterinarian and assistants. The dosages of the assistants who held the animals were higher in the areas of the hands. This study shows the need for additional protective measurements and the implementation of training mechanisms in radiation protection for physicians and assistants who work with portable digital radiology.
