Determination of the Radiation Hazard Indices and Excess Lifetime Cancer Risk in Iraqi Bentonite
Al-Nahrain Journal of Science
The activity concentrations for 232 Th, 238 U, 40 K, and 137 Cs were measured in bentonite samples using high purity germanium detector. These samples were collected from the main distribution markets in Baghdad, the capital of Iraq. The mean activity concentrations for 232 Th, 238 U, 40 K and 137 Cs were found to be 6.10, 5.89, 162 and 1.8 Bq/kg respectively. The results of specific activities were less than the recommended global values by (UNSCEAR, 2000). The radiation hazard indices indoi:10.22401/jnus.21.1.09 fatcat:fyovmb7mjbdnbitpc2bvzaakku
