radiation workers, including radiographers, and veterinarians use appropriate personal dosimeters for dose assessment. In this study, the dose to animals, and the adoptors in the radiological examinations were measured.
Based on the results in the case of animal dosimetry, the average entrance skin dose for all 20 procedures done was 0.36 mGy, with a minimum dose of 0.19 mGy and a maximum dose of 0.53 mGy. In a previous investigation, the dose amount was from 0.62 mGy to the maximum dose of 2.83 mGy( Veneziani et al., 2010). A study examining the dose in the abdomen of 5 animals showed the average dose to be
0.84 mSv, ranging from a minimum of 0.51 mSv to a maximum of 1.87 mSv( Veneziani et al., 2014), while the animals that underwent abdominal imaging in the present study received dose values between 0.20 and 0.53 mSv. Another study showed that the degree of individual exposure among the animals varied greatly, with a range of 0.87 to 2.6 mSv.( Halford and Markham, 1978). A study assessing the dosimetry of mice through the use of TLD( thermoluminescent dosimeter) measurement in combination with micro CT imaging has shown the average radiation dose absorbed by mouse organs to be 760 mSv( Figueroa et al., 2008).
The results of personal dosimetry for the animal adopters showed the average dose to hands, Hp( 0.07), was 0.35 mSv and the average dose to the whole body Hp( 10) was 0.14 mSv. In radiographic procedures, the dose values to the hand s, Hp( 0.07) are higher than the whole-body dose, Hp( 10). Because in some cases, the hands of the staff are exposed to the primary radiation.
5 Conclusion
Maintaining radiation safety for veterinarians, their staff, animal adopters, and animals is crucial as the use of ionizing
