الملخص العربي
A study of long- lived gamma emitting radionuclides in rice consumed in Nineveh Province (IRAQ) were performed. The study targeted the natural radionuclides 226Ra, 232Th and 40K .The rice samples originated from seven different countries. NaI(Tl) detector was used to measure the radionuclides level. The radioactivity concentrations of 226Ra, 232Th and 40K ranged from 51.15 to 109.26 Bq/kg,13.67 to 71.97 Bq/kg and 231.87 to 691.71Bq/kg. In order to evaluate the radiological hazard of the natural radioactivity, radium equivalent activity, gamma absorbed dose rate, internal and external hazard indices , gamma index and finally alpha index have been calculated . Hence rice consumption in Nineveh province (IRAQ) is radiologically safe for the presence of the investigated radionuclides.
