Abstract
The ever-increasing number of X-ray examinations in veterinary medicine calls for appropriate attention to be paid to radiation prevention and control. The initial premise for such an approach is the exact determination of the received radiation dose. Therefore, in order to increase the level of radiation prevention and control in X-ray diagnostics in veterinary medicine, we carried out a research focussing on establishing a model for the determination of radiation dose distribution in a patient's body with greater accuracy than is achievable with models used in human medicine. The research was carried out with two euthanised dogs of the German shepherd breed. For dosimetrical measurements the most common X-ray diagnostic examinations were selected: abdomen radiography in female and hip radiography in male dogs. For dose measurements a previously tested thermoluminescent system (TL) was selected, based on a TLD-700 detector and a TOLEDO 654 computerized reader. In addition to the testing of the dosimetrical system, homogeneity calibration was performed and radiation dose reproducibility was determined. On the basis of achieved results it can be concluded that the described animal model for the determination of dose distribution for X-ray diagnostic radiation yields reliable results and enables us to estimate the risks of ionising radiation associated with various X-ray diagnostic examinations, and thus to increase the level of prevention, and patient protection, in veterinary medicine.
