[1H05] Method for estimating of release rate of radionuclides in nuclear accident from radiation data on the sea

Keywords:Advection diffusion model, Maritime radiation monitoring, Unfolding method

We are trying to establish a new method for quick estimattion of the release rate by combining the dose rate data and the advection diffusion calculation. An unfolding method is applied to solve this inverse problem, where it is one of keys to set appropriate observation points; buoys.
