Abstract

Objective: Present study conducted for the measurement of radiation doses received by the radiation workers due to their direct involvement in handling of unsealed radionuclides for the PET/CT scanning.

Study Design: Quasi Experimental Study.

Place and Duration of Study: PET-CT and Cyclotron Department, Armed Forces Institute of Radiology and Imaging, Rawalpindi Pakistan, from Aug 2020 to Jul 2021.

Methodology: TLD film badges and ring dosimeters, based on LiF:Mg:Ti material, were used for the detection and measurement of radioactivity. The measurements were performed for both whole body and extremity (fingers) dose measurements.

Results: The measured radiation doses were in the range of 362.75 mSv/y to 409.74 mSv/y and 0.08 mSv/y to 4.35 mSv/y for extremities and whole body, respectively. Number of injections was calculated for extremity workers and found to be 720±27 injections per worker per year.

Conclusion: The measured results clearly show that the annual doses for whole body (20 mSv/y) and extremity (500 mSv/y) of radiation workers are under the recommended limits. However, radiation workers with direct access to radioisotopes were more exposed to radiation. The results of present study were also in good correspondence with the published data.
