영문 초록

Purpose The goal for this study is to figure out that medical staff except Nuclear Medicine Department could be exposed to radiation from the patients who take Nuclear Medicine examination. Materials and Methods Total 250 patients (Bone scan 100, Myocardial SPECT 100, PET/CT 50) were involved from July to October in 2015, and we measured patient dose rate two times for every patients. First, we checked radiation dose rate right after injecting an isotope (radiopharmaceutical). Secondly, we measured radiation dose rate after each examination. Results In the case of Bone scan, dose rate were 0.0278±0.0036 mSv/h after injection and 0.0060 ± 0.0018 mSv/h after examination (3 hrs 52 minutes after injection on average). For Myocardial SPECT, dose rate were 0.0245 ± 0.0027 mSv/h after injection and 0.0123 ± 0.0041 mSv/h after examination (2 hrs 09 minutes after injection on average). Lastly, for PET/CT, dose rate were 0.0439 ± 0.0087 mSv/h after examination (68 minutes after injection on average). Conclusion Compared to Nuclear Safety Commission Act, there was no significant harmful effect of the exposure from patients who have been administered radiopharmaceuticals. However, we should strive to keep ALARA(as low as reasonably achievable) principle for radiation protection.
