Abstract
In nuclear medicine, the imaging process used to diagnose diseases and to examine the functions of organs is carried out with radiopharmaceuticals containing radioisotope. In this study, the amount of external radiation emitted from bone scintigraphy patients who were given 99mTc-MDP kit was examined. The measurements have been performed using FLUKE Victoreen ASM 990 portable detector at Nuclear Medicine Department Medicine Faculty in Tokat Gaziosmanpasa University. The external dose rate values have been measured at 0.50 m, 1.0 m, 2.0 m and 3.0 m away from the patient considered as the source of radiation. All measurements have been taken within approximately one hour and 10 minutes at 10 minutes intervals after injection of the pharmaceutical. In this study, the highest external dose rate value is measured 13.81 μSv h-1 from 0.50 m distance after 30 minutes from the radiopharmaceutical injection and the lowest external dose rate value 1.53 μSv h-1 is obtained from 3.0 m distance after 60 minutes. Then, dose rate values per unit activity were calculated and the highest value was found as 20.57 μSv h-1 GBq-1 30 minutes after injection at 0.50 m. The results obtained were compared with other studies in the literature.
