It is important to estimate the release rate of radionuclides from a damaged nuclear power plant in order to understand the radiation effects on the surrounding environment. So, the reverse problem may be valid, which is a method to quickly estimate the release rate from the dose rate to be measured at observation points apart from the source. In order to realize this process, it is necessary to acquire plural observation data with high precision. So, we focused on radiation measurement on the sea, which is not affected by geographic obstacle and can be installed arbitrary points. Now, we try to use multiple buoys which equipped with suitable radiation detector, GPS device, communication device, and so on. In particular, we aim to establish a calculation method where we can estimate the release rate from the observation data, using The Lagrangian Model.
