Abstract
Flour is a powder made from grains which rich in starch, where 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 average concentration of 226Ra, 232Th, 40K% radionuclide in (ppm) units and Radium equivalent activity Raeq (Bq.kg-1) was (0.703, 5.874, 2.869 and 109.615) respectively, also calculate the ratio ( 232Th - 226Ra, 40K - 226Ra, 40K - 232Th) were measured in 15 flour samples using a gamma ray spectrometer with average values (4.097, 152.045 and 56.889) respectively. From the result we found that the ratio (40K - 226Ra) and (40K - 232Th) were higher than the average worldwide. Annual gonadal equivalent dose AGED (mSv.y-1),it included a rise above the universally accepted health limit, the average of total annual committed effective dose AACED (mSv.y-1) was higher than limits permissible globally for adult , children and infant. Finally WE found Excess lifetime cancer risk (ELCR􁈻 for adult, children and infant which were (0.004, 4.638E-05 and 1.60354E-05) , which does not fall within the limits permissible globally for adults , while it is universally accepted for children and infants. We can consider this study as a baseline for future studies.
