Evaluation of occupational radiation dose due to 99mTc and 131I based examinations
Abstract
Aims: This study investigates the individual organ doses and the impact on effective dose of radiation emitted from radioactive sources.
Methods: In the conducted research, the standing ICRP adult male phantom defined as the phantom material in the Visual Monte Carlo dose calculation program (VMC) was used. Subsequently, doses incurred were calculated by defining different doses, distances, and durations for 99mTc and 131I radioactive sources.
Results: Simulation durations (exposure durations) were set at 1 minute and 5 minutes for comparison. The results indicated that both in 1-minute and 5-minute exposures, the doses remained below the ICRP's recommended annual dose limit of 50 mSv/year for occupational exposure.
Conclusion: It was observed that the organ dose and effective dose vary with the source strength and exposure duration. Regardless of how low the doses may be, individuals working in radiation fields must make greater efforts to reduce radiation doses by adhering to the ALARA principles.

Keywords : Effective dose, Monte Carlo, VMC program, ICRP Phantom
