Dose of the lens, Radiation workers, I-123, Tc-99m, FDG
It is suggested that the dose limit recommended in the Enforcement Decree of Korea's Nuclear Safety Act should not exceed 150 mSv per year for radiation workers. Recently, however, ICRP 118 report has suggested that the threshold dose of the lens should be reduced to 0.5 Gy and the mean dose should not exceed 50 mSv per year for an average of 20 mSv over 5 years. Based on these contents, I-123, Tc-99m, and FDG, which are radioisotope drugs that are used directly by radiation workers in the nuclear medicine department in Korea are expected to receive a large dose of radiation in the lens in distribution and injection jobs to administer them to patients. Since it was suggested that the dose equivalent of the lens presented in ICRP 103 can be measured by using dose equivalent of skin for the monitoring purpose, this study measured the lens exposure dose of the radiation workers in the nuclear medicine department by using ED3 Active Extremity Dosimeter, an extremity dosimeter. The measured values were analyzed by the work of the radiation workers in the nuclear medicine department, the presence or absence of shielding, and the source. In addition, by checking the work, presence or absence of shielding of each source, we performed descriptive statistics by using the SPSS Version 21.0 for the exposure dose given to the lens per 1 mCi. As a result of measuring distribution and injection tasks for each worker, the annual dose is relatively low, but it is difficult to determine the exact dose because it is limited to distribution and injection tasks. However, by using the Dose Calibrator by using the result of analyzing the exposure dose per 1 mCi, it is expected that the radiation workers in the nuclear medicine department themselves can judge the expected exposure dose to the lens. In addition, since continuous exposure may cause lens opacity and cataract, it is thought that radiation safety managers and related regulatory agencies should manage and continually study the exposure dose of the lens.
