Atmospheric trajectory analysis of cesium-137 from proposed nuclear power plant site in Bangka Island, Indonesia

Environmental risk assessment for nuclear power plant (NPP) operation is important to monitor the level of radionuclide concentration in the atmosphere and to determine the health risks associated with potential external radiation exposure. A NPP site was proposed in Bangka Island, Indonesia, 554 km...
