title: Characteristics of airborne radionuclides concentration in a coastal environment.
abstract: Airborne radionuclides from the Fukushima nuclear power plant accident in 2011 were measured in 12 regional monitoring stations in Korea. The Gangneung (GN) monitoring station located in a coastal region almost always has a higher radioactivity concentration of airborne radionuclides than any other station. The possible cause of this higher concentration was analysed in terms of the local meteorology and topography. The increase in surface concentrations of radionuclides at the GN region might be attributed to the downslope windstorm, temperature inversion and coupled sea breeze and mountain flows.
