Radionuclide concentrations and Estimation of the Corresponding Annual Effective Dose due to gamma radioactivity in Powdered Milk in Babylon governments

Abstract

Natural radionuclides in ten of the most available types of milk powder among various brand names that collected from local markets in Babylon government have been analyzed by means of a gamma –ray spectrometry NaI(TI) and estimated of the annual effective dose intake of the radionuclides. The concentration of226 Ra, 232Th and 40K have been found to vary from (57.2645±1.853031) Bqkg−1 to(0.299814±0.1340 ) Bqkg−1 with an average value of (20.67518±0.134077) Bqkg−1,from (36.7284±1.422407 ) Bqkg−1 to (0.37037±0.066679) Bqkg−1 with an average value of.( 12.41975±0.65718 ) Bqkg−1and from (481.521±5.65807) Bqkg−1 to (268.0537 ± 0.299814) with average value (377.5035±4.460395) Bqkg−1 respectively,the result showed that the concentration of radionuclides exceeded the result reported in the world wide. The dose due consumption of milk by public has also been determined and has been below the dose limit recommended by world health organization.
