Abstract: In this study of radioactive levels for animal feed which are negotiable Iraqi’s markets .The No. of collected samples are twelve from different types and originating, the measured spectrum are made by using NaI (TI) detection which has dimensions “3*3” crystal. From the spectrum results were the specific activity about from (3.0501±2.723)-(9.803±2.832), the range (4.8802±2.75341) Bq kg-1 for 238U while the specific activity about from (0.527±0.583)-(1.583±0.611), the range (0.9532±0.58695) for 232Th, the activity concentration for 40K about from (172.5±16.47)-(80.463±9.583). Then, Req was calculated, it was about 10.488-18.486 Bq kg-1, the internal Hazard index was calculated (Hin) which was about 0.0387-0.0767 while external Hazard index (Hex) was about 0.0304-0.04052.
