Abstract: Original calculation algorithms are proposed for absorbed doses in the thyroid gland and thymus of rats at single income of 131I that enable to simplify the calculations and at the same time ensure high reliability of results in the range of input activities of 1 - 115000 Bq. According to the algorithms, the program is developed in the MATLAB environment, adapted for use on Windows running PC. Relative error of calculations is ±2 %.

Keywords: 131I isotope, thyroid, thymus, dose formation, optimization.
