Evaluation of the radiological hazard in some dried fruit and grain samples in Iraqi Markets by Using of gamma ray Spectroscopy

Abstract

Abstract The activity concentrations of 226Ra, 232Th and 40K have been measured by using of gamma spectroscopy for fifteen samples fall under the consumed food group (six type of dried fruit and nine types of grain) at local markets in Baghdad. The average of activity concentration values of 40K, 232Th and 238U were 324.4±28.5 Bq/Kg, 3.66±0.20 Bq/kg and 3.44±0.58 Bq/kg, for the dried fruit samples, 302.3± 98.9, 4.8±1.5 and 4.29 ±1.4 Bq/kg, respectively. For the grain samples, radiation hazard indices, the annual effective dose, internal and external risk, lifetime cancer, and the doses of ingestion, were all doses values within the international borders allowed. Thus, Food the dried fruit and grain in Baghdad is safe for human consumption and it has no heath effect.
