Investigation of natural radionuclides in foods and waters in China and evaluation of internal dose to public

Abstract

In order to obtain background radiation levels of natural radionuclides in foods and waters in China, the determination and analysis of water and food samples have been completed by organizations of radiological protection from 28 provinces, autonomous regions and three major cities. Ranges of specific activity of natural radionuclides for U, Th, Ra, K, Pb and Po are (2.2 {approx} 25.5) x 10 {sup -2} Bq/kg, (0.5 {approx} 6.9) x 10{sup -2} Bq/kg, (3.4 {approx} 25.5) x 10 {sup -2} Bq/kg, (25 {approx} 420) x 10{sup -2} Bq/kg, (3.9 {approx} 55) x 10{sup -2} Bq/kg and (2.7 {approx} 58) x 10{sup -2} Bq/kg, respectively. Samples of drinking water were taken from tap water or well. The average concentrations in tap water and well water are 2.8 x 10{sup -2} Bq/L and 3.7 x 10{sup -2} Bq/L for U, 0.8 x 10{sup -2} Bq/L and 1.3 x 10{sup -2} Bq/L for Ra, 0.07 x 10{sup -2} Bq/L and 0.06 x 10{sup -2} Bq/L for Th, 0. 3 x 10{sup -2} Bq/L and 1.1 x 10{sup -2} Bq/L for Pb and 0.3 Bq/L and 0.5 Bq/L for Po respectively. The annual intakes by ingestion have been calculated. The annual intake of male  More>>

The annual intakes by ingestion have been calculated. The annual intake of male adult from six main natural radionuclides is about 205 Bq. Among them 64% of total intake of U is from drinking water. The contributions from grains to the total intake of Ra, Pb and Po are 55.7%, 59.7% and 70% respectively. The total annual average effective dose equivalent of 6 natural radionuclides for male adult in China is about 310 {mu}Sv.}
