摘要：The activity concentrations of 226 Ra 232 Th, and 40 K radionuclides were measured for 10 brands of powdered milk samples consumed in Iraq,which are imported from different countries.The main detected activity corresponding to 40 K with average activity of 290.661 BqKg -1 , while the average activities of 226 Ra and 232 Th were below the detection level (B.D.L.).Results are compared with those of different countries worldwide.The total average annual effective doses due to intake of 40 Kfrom the ingestion of the powdered milk for children (2-7, 7-12, 12-17)y and adults (≥ 17y) were estimated to be82.21, 50.90, 29.75 and 22.55 µSvy -1 , respectively. These results indicate no significant radiation dose to the public. The resulting data may serve as base-line levels of activity concentration in powdered milk in the area of study.
