Radioactivity in Food can be polluted with many types of radioactive materials due to natural and a nuclear emergency. The aims of this work are to govern the specific activity 238U, 232Th and 40K as well as calculate the annual effective dose due to the ingestion of cerelac baby food that available in Iraqi markets. Samples were collected from local market in Najaf from different countries of origin. The levels of 238U, 232Th, and 40K were determined using gamma ray spectrometer. The results show that, the average specific activities for 238U, 232Th, and 40K were 8.49±2.18, 4.50±0.80 and 223.85±29.22 Bq/kg, respectively. However, the average value of radium equivalent activity and internal hazard index were 32.16±2.77Bq/kg and 0.109±0.012 respectively. whereas the total average annual effective dose caused by 238U, 232Th, and 40K for children is estimated to be 0.571±0.05 mSvy. The values found for specific activity and the annual effective dose in all samples of cerelac baby food were lower than worldwide median values for children; therefore, these values are found to be safe.
