Abstract
The activity concentrations of natural (40K) and anthropogenic (137Cs) radionuclides were measured in the 30 most commonly consumed foods in Korea. The average activity-concentrations of 40K and 137Cs were 67 Bq kg?1 and 46 mBq kg?1 fresh weight of food, respectively. The total annual intakes of 40K and 137Cs by humans were 14915 and 3.64 Bq year?1, respectively. The calculated mean annual effective doses from ingestion of the investigated foodstuffs were 92 μSv for 40K and 0.047 μSv for 137Cs. Our results can provide useful background information on radiation protection in Korea, and in other countries as well.
