Wheat and rice are among the main ingredients on which the Iraqi populations depend. The important part of this is detected knowledge the uptake radionuclide in this cereal, no less in admiration of any personal health harmful. In this study, we measured the concentrations of naturally occurring radioactive nuclides in cereals and the corresponding soil collected from agricultural fields in Al Shamiyah, Al- Diwaniyah governorate in Iraq using nuclear detector of tracks (CR-39). The mean activity concentration of uranium (ppm) in soil, wheat and rice samples were found to be 1.18 ± 0.19, 0.02 ± 0.001 and 0.88 × 10 -2 ± 0.00085, respectively. Factors of transfer from soil-to- cereals were limited to be 0.012 and 0.017 for wheat and rice. The results of TFs of 238 U were found to be in agreement with previous studies values, these results refer to radionuclides movement were very low in these soils. Results have been shown the uranium concentration to be less than permissible limit (11.7 ppm) proposed by UNSCEAR. On the other side, results noticed there are no pose significant threats to health of human, the edible cereals being safe to consume.
