Sažetak
An ever increasing number of X-ray examinations in veterinary medicine calls for appropriate attention to the radiation prevention and control, and the starting premise for such approach is the exact determination of the received radiation dose. Therefore, in order to increase the level of radiation prevention and control in the X-ray diagnostics in veterinary medicine, we carried out a research focused on the determination of a model for the determination of the radiation dose distribution in a patient's body with a higher accuracy than that achievable with the models used in human medicine. The research was carried out with two dogs of the German shepherd breed. For the dosimetrical measurements the most common X-ray diagnostic examinations were selected: the abdomen radiography in female and the hip radiography in male dogs. For dose measurements a thermoluminescent system (TL) was selected, based on a TLD-700 detector and a computerized reader TOLEDO 654. The selected system was previously tested at the "Ru� er BoÁkoviÜ" Institute with the radiation exposure at 137Cs source, at a dose rate of 0.91 mGy/h and 1 m distance. In addition to the testing of the dosimetrical system, the homogeneity calibration was performed and the radiation dose reproducibility was determined. On the basis of the achieved results, it can be concluded that the described animal model for the determination of dose distribution for the X-ray diagnostic radiation yields reliable results and enables us to estimate, on the basis of the established surface radiation dose, both the radiation dose received by individual organs and the risks of the ionizing radiation associated with various X-ray diagnostic examinations and thus to increase the level of prevention and patient's protection in veterinary medicine.
