Abstract

The specific activity of Uranium (238U),Thorium (232Th) and Potassium (40K) were measured in different brands of cooking oil that are available in Saudi Arabia markets. The gamma spectrometry method with high-purity germanium (HPGe) detector was used. The results indicate that the activity concentrations measured  for 226Ra varied  from 0.23 to 6.05 Bq l-1 , 232Th varied from 0.68 to 2.89Bq l-1  and 40K from 1.32 to 21.81Bq l-1.The corresponding average activity concentrations of 226Ra,  228Th and 40K were found to be 2.41, 0.85 and 8.87Bq l-1, respectively. The total annual effective dose was estimated to be 9.51?Svy-1 whichis less than the world total dose value 290 ?Svy-1 for all food reported by  UNSCEAR 2000. The results show that all the examined samples do not create any significant source of radiation hazard and safe for the public health.
