Effective doses for external exposure from the photon radiation field of soil contamination

Abstract

Organ and effective doses of adult for external exposure to photons uniformly distributed in soil were calculated using a MIRD-5 type phantom and MCNP code. The calculations were performed for mono-energic photon sources with source energies from 0.01 MeV to 5 MeV. The effective dose coefficients in this calculation using MCNP code were compared to the calculated results in report of Keith F. Eckerman và Jeffrey C. Ryman.
