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.
