초록
The current study had the radiation workers working in nuclear medicine department wear individual exposure dosimeters in the front and in the back, considering the underestimated individual exposure to radiation from patients undergoing radiological medicine treatment. The utility of the device was assessed in the study. From January 2015 to February 2015, 85 radiation workers working in 11 Korean nuclear medicine department were analyzed by their workplace and their specialty; PET-CT and gamma cameras were used to analyze the radiation exposure in the front and the back of the radiation workers. This revealed that the exposure measurement and assessment using the dosimeter worn on the front were not underestimated. However, because this measurement did not take into account the adequate radiation weighting factor for the back side dosimeter, a radiation exposure assessment algorithm for the back side radiation exposure must be developed, which can be used as a basic data for introducing double dosimeter for radiation workers working in nuclear medicine department.
