Assessment of bioaccumulation radioactivity in Iraqi wheat grains

Bioaccumulation radioactivity of five wheat grain varieties (three local and two imported) was investigated by using high-resolution gamma spectroscopic system employing (NaI), in addition to some chemical properties of these grains were studied. The obtained results show that (Al-Zhara?a and Zer) brands have greatest moisture percent with mean value (9.37±0.097 and 9.19±0.188), respectively. The Zer brand recorded highest value of gluten 22.52±0.36 mg/gm. The obtained results of the radioactivity measurements of the five wheat grains were show that the levels of radioactive materials in the studied samples are below the detection levels (BDL).
