Abstract

We investigated the amounts of radiation exposure from , , and which are three major radionuclides naturally residing in soil of the Korean peninsula. The experimental results showed that the concentrations of the radionuclides were 15.777.27, 290.0573.92 and 750.30165.38 Bq/kg respectively. The absorbed dose rate based on the measured concentrations was 213.7646.37 nGy/hr, while the spatial gamma absorbed dose rate measured in the same region was 123.9019.18 nGy/hr. The effective dose rate was 0.26 mSv/yr, which is significantly higher than the world average effective dose rate 0.07 mSv/yr provided by the UNSCEAR.
