Differences in photon personal dosemeter responses under ideal irradiation geometries and approximate ones with a point isotropic source; MCNP simulations with an MIRD phantom

In accident dosimetry and epidemiological studies, it is necessary to convert the readings of personal dosemeters calibrated in terms of operational quantities into the effective doses or organ absorbed doses for further analysis. For this purpose, an attempt has been made to experimentally evaluate the response of personal dosemeters mounted on an anthropomorphic phantom irradiated under conditions that simulate typical exposure geometries in workplaces. To assess the differences in personal dosemeter responses under the ideal AP, ROT, and ISO irradiation geometries and approximate experimental ones with a point photon source placed at various distances (2-4 m), an MCNP Monte Carlo simulation was made with a modified MIRD humanoid phantom with arms. As a result, the simulation revealed a systematic deviation of up to 4%.
