Abstract

|
The soils and plants were sampled from 26 sites of Deogpyeongri, Goisangun, which had been found to be one of the uranium deposit areas. Uranium levels of the samples were determined and the amount of uranium intake by the residents through the food-chains was estimated.
The average uranium concentration of Deogpyeongri soils was 15.5ppm with a range of from 4.9 to 43.6ppm showing rather higher values than those of control area, Yangjugun and Icheongun, Gyeonggi-do. The average uranium content of the plant samples from Deogpyeongri was 0.69ppm, about twice the uranium concentration of the control samples.
The daily intake of uranium by an adult lived on the agricultural food stuffs produced in Deogpyeongri, was estimated to be about 247㎍, eqivalent to 0.83×10^(-4)μCi, which is much higher activity compared to the daily intake cf uranium by New York citizen, 1.3㎍. However the calculated uranium level accumulated in the human body of Deogpyeong area was 2.03×10^(-4)μ which is still lower than 0.2μCi, the maximum permissible burden in total body recommended by the ICRP.
