We developed an atmospheric dispersion calculation method that can respond to various needs for dispersion prediction in nuclear emergency and prepare a database of information useful for planning of emergency response such as environmental monitoring. By applying this method to the area around a nuclear power station, we examine its validity and effectiveness.
