Investigation of the effects of radionuclides used in nuclear medicine on organ dose and effective dose
Abstract
Aims: The aim of this study is to investigate the effects of 68Ga, 18F, 89Sr, 13N, 133Xe and 131I radionuclide sources on organ doses and effective doses at different distances.
Methods: In this study, radionuclides commonly used in nuclear medicine applications were defined in the VMC dose calculation software to determine organ doses and effective dose values at varying distances. Additionally, the dose rates of each radionuclide were obtained using the Rad pro calculator online program.
Results: For different radionuclides at a 10 mCi dose, average dose rate measurements were conducted at varying distances. Specifically, 13N and 89Sr delivered the highest doses to certain organs, whereas 133Xe ve 131I resulted in lower doses. The effective doses at 100 cm for 68Ga, 18F, 89Sr, 13N, 133Xe and 131I sources were determined to be 2.72 µSv, 2.94 µSv, 2.50 µSv, 2.84 µSv, 0.91 µSv, and 1.16 µSv, respectively. The effective doses at 150 cm for 68Ga, 18F, 89Sr, 13N, 133Xe and 131I sources were determined to be 1.56 µSv, 1.49 µSv, 1.30 µSv, 1.46 µSv, 0.14 µSv, and 0.58 µSv, respectively. As the distance increased, radiation exposure levels decreased.
Conclusion: In this study, radiation exposure decreased significantly with distance from the source, demonstrating the importance of maintaining distance and applying ALARA principles in clinical settings. Furthermore, avoiding close proximity to the radiation source and utilizing appropriate shielding methods are crucial in minimizing radiation exposure.
