In the event of environmental contamination with radioactive materials, one of the most dangerous materials is 137Cs. In order to evaluate the radiation doses involved in an environmental contamination of soil, with 137Cs, we carried out a computational dosimetric study. We determined the radiation doses conversion coefficients (CC) for E and HT, using a male and a female anthropomorphic phantom, coupled with the MCNPX (2.7.1) Monte Carlo simulation software, for three different types of soil. The highest CC[HT] values were for the gonads and skin (male) and bone marrow and skin (female). We found no difference for the different types of soil.
