  Natural background radiation is the major source of human exposure to radioactive materials. Foodstuffs naturally contain radioactive mineral contents. The aim of this study is to determine the levels of natural radioactivity (226Ra, 232Th and 40K) in wheat flour, pasta, rice and corn in the Iraqi market. Na (Tl) detector was used to measure the concentration activity of 226Ra, 232Th and 40K in four type of foodstuff. The average activity concentrations of 226Ra, 232Th and 40K were found to be 4.498, 7.621 and 223.259 Bq.kg-1(dry weight), respectively, Iα, AUI and Hin were lower than 1 ,Absorbed Dose Rate in air (DR) 15.611 nGy h−1, Annual Gonadal Dose equivalent (AGDE) 111.252 μSv.y−1, Annual Effective Dose Equivalent (Eav.) 0.4560 mSv.y−1 and Excess lifetime cancer risk(ELCR) 1.5961× 10-3 also measured in wheat flour samples. While were found 4.095, .. Read More»
