Flour is a nutritious type of food that is widely consumed by various age groups in Iraq. This study investigates the presence of long-lived gamma emitters in different type of flour in Iraqi market. Uranium ( 238 U), Thorium ( 232 Th) and Potassium ( 40 K) specific activity in (Bq.kg −1 ) were estimated in (15) unique kinds of flours that are accessible in Iraqi markets. The gamma spectrometry method with a NaI(Tl) detector has been utilized for radiometric measurements. Likewise right now have determined the internal hazard index. It is found that the specific activity in Flour samples were varied from (13.73± 1.89) Bq.kg −1 to (2.60± 0.30) Bq.kg −1 with an average (8.75) Bq.kg −1 for 238 U, For 232 Th From (67.79± 0.44) Bq.kg −1 to (9.96± 0.14) Bq.kg −1 with an average (21.88) Bq.kg −1 and for 40 K from (2680.74 ± 23.60) Bq.kg −1 to (283.70± 3.41) Bq.kg −1 with an average (133.09) Bq.kg −1 . Also, it is found that the Outdoor and indoor annual effective absorbed dose equivalent also (Hin) hazard indices was (0.302±0.014) and average annual committed effective dose(0.2205±0.030) mSv.y −1 in the flour samples. This study prove that the natural radioactivity and radiation danger records were low also estimated cancer risk has no significant health hazard in Iraqi Flour.
