Paper Abstract

A new set of conversion coefficients from kerma free-in-air to absorbed dose and to effective dose for external photon exposure with incident energies between 15 keV and 10 MeV under six standard irradiation geometries have been calculated using the Visible Chinese Human (VCH) computational model, which was developed on purpose of radiation dosimetry and protection. The whole-body voxelized geometry of VCH was mirrored from the high quality cryosectional photographic color images and was representative for the average physical characteristics of Chinese population. Dose discrepancies in comparison with other datasets are mainly due to anatomical differences. Detailed results from the VCH model are able to complement current dosimetric data in the realm of Radiology. The investigation on simulative particle transport and dosimetry calculation provides quantitative references for the study of anthropomorphic models.
