Calculation and Approximation of Radial Dose Function of Iridium Sources

Background and Objectives: The purpose of this paper is to investigate optimal fitting parameters for approximating radial dose function of Iridium sources. Calculations were performed using written by authors source code based on GEANT4 library package designed to simulate particle transport processes using Monte–Carlo method. Results: Following parameters of the source were determined: dose rate constant, radial dose function and anisotropy function. Obtained satisfactory coherence with other researchers’ data.
