The external and internal absorbed dose of ICRP phantom calculated with THUDose_pd and ICRP Publication

The external irradiation benchmarking leveraged insights from ICRP publication 116. This evaluation contrasted dose conversion coefficients for ISO irradiation with monoenergetic photons and AP irradiation with monoenergetic neutrons. The internal irradiation benchmarking drew from the research of Zankl et al., which examined the SAF values of organs when subjected to electron and photon irradiation.ICRP Publication 116 deduces reference conversion coefficients for both the effective dose and organ-absorbed doses under various external exposure conditions. This is based on the ICRP reference phantoms for both genders. It offers data from external beams of monoenergetic photons, electrons, positrons, and neutrons with configurations such as AP, PA, LLAT, RLAT, ROT, and ISO. In our assessment, the focus was on validating dose conversion coefficients specifically for the ICRP reference male, choosing monoenergetic photons and neutrons ranging from 10 keV to 10 GeV for the process.Zankl et al. employed the ICRP reference male and the EGSnrc Monte Carlo program to deduce SAF values for photons and electrons, considering varied source organs and target organs. To ascertain the precision of SAF values derived using THUDosePD, the ICRP reference male served as the basis for calculating the SAF values for electrons moving from the kidney to three distinct organs: the kidney itself, the adrenals, and the liver. The outcomes of this exercise were juxtaposed against Zankl’s findings
