Survey monitoring of environmental radioactivity in Gangneung area

The objectives of the project are to get a systematic data for the distribution of environmental radioactivity levels in Gangnung provinces, and use them as a baseline data for the health of the peoples. To monitor the environmental radiation/radioactivity, gross beta activities and gamma exposure rate in the airborne dust, fallout, precipitation and tap water were measured in Kanunung province during the period of January 1 - December 31, 1997. Soils, waters from drinking water reservoirs, fishes, agricultural and animal products were sampled from some selected areas to make sure of the effect of the fallout due to the atmospheric weapons test. In 1997, the average annual of Gross beta activities in the airborne dust, fallout, precipitation and tap water measured in Kanunung province were 7.51 ± 1.27 mBq/m3, 21.6 ± 2.4 MBq/km2 - 30d, 69.7 ± 12.6 mBq/L, 36.5 ± 28.7 mBq/L, respectively, all of which were similar to the past data. The average annual of gamma exposure rate mesured in Kanunung was 11.4 μR/h, which was all about the past data. Also, The environmental samples were made for the analysis
