Abstract

Background and Aim: Most radioactive materials used in Nuclear Medicine are gamma emitters. Gamma range is relatively large, so the Nuclear Medicine staff is exposed to external exposure by gamma. The aim of the present study was to estimate the dose which is received by staff during different diagnostic methods in a Nuclear Medicine center. Methods: This study is a descriptive, cross-sectional study. The studied components include the amount of radiation of the staff in the imaging stage of patients and the injection of Radiopharmaceuticals to patients at different intervals. A total of 60 patients and 8 staff were included in the study. Data was collected in terms of compliance with the dose limits set by the Atomic Energy Organization (20 mSv/year) based on descriptive statistics, such as minimum dose, maximum dose, the mean and standard deviation of analysis, and comparisons through student t-test in SPSS. Results: The average amount of irradiation recorded for staff due to imaging process ranged from 0. 03±, 0. 01 to 0. 32±, 0. 08 μ, Sv/h and 0. 05 ±,0. 03 to 0. 43 ±,0. 04 μ, Sv/h, when Radiopharmaceuticals were injected into the patient. Conclusion: The amounts of the doses received were in good agreement with other studies, and did not exceed the dose set for occupational exposure (20 milli Sieverts per year). The Dose Received by staff decreases as the distance from the patient increases and the duration of communication with the patient decreases.
