Abstract

Background and Objective: 131 I RADIONUCLIDE has been widely used for treatment of thyroid cancer and hyperactivity. In this regard the accurate calculation of ABSORBED DOSE in THYROID GLAND and other organs is important. Materials and Methods: In this study, according to MIRD METHOD, MCNP CODE was used for calculation of ABSORBED DOSE of 131I radioactive sources in any thyroid with specific mass and size. Results: The results of two different geometries; spherical and cylindrical shapes for each lobe of thyroid were compared. The results show when the thyroid mass increase from 20gr to 70gr, the ABSORBED DOSE per one disintegration increases 4.2%.Conclusion: These results firstly indicate that instead of using the total mass of thyroid in iodine therapy, it would be better to use the calculated active mass of thyroid. Secondly, the variation of ABSORBED DOSE per disintegration of 131 I should be considered for the measurement of source activity in treatment of thyroid hyperactivity or cancer.
