Abstract
The concentrations of natural and artificial radionuclides in soil and gamma ray dose rate in air at 233 locations in Korea have been determined. The national mean concentrations of {232}Th, {226}Ra, {40}K, {137}Cs and {90}Sr in soil were 60{pm}31, 33{pm}14, 673{pm}238, 35{pm}9.3 and 5.0{pm}3.4 Bq kg{-1}, respectively. The mean gamma-ray dose rate at 1 m above the ground was 7918 nGy h{-1}. {137}Cs concentration had highly significant correlation with organic matter content and cation exchange capacity. {90}Sr concentration had slightly coherent with pH. The results have been compared with other global radioactivity and radiation measurements.
