Monte Carlo modelling of human body for dose conversion coefficients of Cs-137 in soil of the Eastern Black Sea region of Turkey

Abstract

Absorbed dose conversion coefficients for a human body standing on the soil surface were calculated for Cs-137 in the soil of Eastern Black Sea region of Turkey using the Monte Carlo simulation method. The results were given in nGy h(-1) per Bq cm(-2) as a function of depth. Simple numerical integration of this function multiplied with the known specific activity as a function of depth gives the absorbed dose conversion coefficients for any distribution of Cs-137 in soil. Gaussian distribution of Cs-137 in the soil was considered for calculations.
