Calculation of Internal Radiation Dose due to Acute Ingestion of 60Co by Adopting HATM Model

Abstract

Activity of radionuclide, absorbed dose, committed equivalent dose, committed effective dose due to acute intake of 1 Bq of 60Co through ingestion have been calculated by using locally developed software that has been prepared basing on the human alimentary tract model. Due to ingestion, maximum radiation dose is deposited in the alimentary tract, which consists of seven tissue compartments, e.g., OC, OP, ST, SI, LC, RC, and RSC. Tissue masses of alimentary tract for Bangladeshi people have been considered to calculate the abovementioned quantities for different age groups such as newborn, 1 yr, 5 yrs, 10 yrs, 15 yrs (male and female) and adult (male and female). Regarding age the variation of absorbed dose, committed equivalent dose and committed effective dose follows the sequence: newborn gt;1 yrgt; 5 yrgt; 10yrs gt; 15 yrsgt; adult female gt; adult male.
