Abstract
In this work, the conversion coefficients from air kerma to the eye lens dose were calculated for photon exposures using the detailed eye and head Monte-Carlo (MC) model with the Chinese adult parameters. To verify the MC model and the simulation method, the conversion coefficients from fluence to the eye lens dose for mono-energy electrons (0.7-12MeV) were calculated and compared with other studies. Then the conversion coefficients from air kerma to the doses in the entire lens and in the sensitive volume were calculated, respectively, for mono-energy photons (0.01-50MeV) at different incidence angles (0-90°, in step of 15°). A small difference was found between the calculated conversion coefficient and the ICRP recommended value. The difference could be mainly due to the difference in their geometry characteristic of the eye and head models. In addition, the uncertainty analysis of the calculated conversion coefficients was performed in detail. The calculated dose conversion coefficient of the eye lens can be used to evaluate the eye lens dose for Chinese occupational staffs in external photon fields. And it can be used to determine the personal absorbed dose in the eye lens Dp lens in photon reference radiation fields.
