In the present work, Uranium ( 238 U), Thorium ( 232 Th) and Potassium ( 40 K) specific activity concentration in (Bq/kg) was measured in five different types for wheat flours that are available in the Iraqi markets. The gamma spectrometry method with an NaI (Tl) detector has been used for radiometric measurements. Calculations of radium equivalent activity, annual effective dose equivalent, external hazard index (H ex ), internal hazard index (H in ), representing gamma index and gamma dosedoi:10.21123/bsj.2021.18.3.0649 fatcat:klwoew3iwvbc7dfxbnsoy5dz5e
