Comparison of alpha equivalent dose and equivalent annual reproductive dose in flour / Iraq.

Flour is a powder made from grains such as wheat, barley, rice, etc., or any crops rich in starch, also flour is the main raw material in making basic foods such as bread. because of the increased incidence of cancer, this study was conducted to assess the concentration of radionuclide specific activity concentration in the most common food in Iraq (different types of Cereal flour) and to estimate its radiative forcing in the long term. For this purpose, the ratio (²³²Th - ²²⁶Ra , ⁴⁰K - ²²⁶Ra , ⁴⁰K - ²³²Th) were measured in 16 cereal flour samples using a gamma ray spectrometer with average values (0.153 , 34.550 , 227.810) respectively, the result showed that the ratio concentration values (⁴⁰K - ²²⁶Ra), (⁴⁰K - ²³²Th) were higher than the average worldwide. also calculated some hazard indices alpha index(Iα) gamma index(Iγ), indoor absorbed dose(D_in), outdoor absorbed dose (D_out) ,annual gonadal equivalent dose (AGED) , the annual committed effective ingestion dose (AED) , finally found cancer risk (for adult, children , infant and workers which were (0.0001, 1.16E-04 , 3.64E-06 and 0.00077) respectively within the permissible limits. The radiation hazard indexes for all samples were lower than the satisfactory values. [ABSTRACT FROM AUTHOR]
