RADIATION DOSE DISTRIBUTION OF A PLAIN RADIOGRAPHY ROOM AND COMPUTED TOMOGRAPHY ROOM IN A VETERINARY HOSPITAL

Abstract

Abstract Thermoluminescent dosemeters (TLDs) were attached to the walls of a plain radiography room and a computed tomography (CT) room, control rooms and corridors to measure the radiation dose. The types of animals scanned and scan parameters were analysed. Dogs and cats accounted for the largest proportion of animals, a combined total of 96.0%. Distributions of tube voltage and tube current-time product are presented. In the CT room, the dose at the angle of the gantry opening was higher than that on either side of the gantry. The study developed equations that may be useful to assess the dose for staff standing in radiography rooms. The personal annual doses for the controlled and uncontrolled areas were lower than the recommended dose limit. The annual doses for personnel and nonworkers were also within the acceptable level for radiation safety.
