Abstract
The 'source term' including the time evolution of the release rate to the atmosphere and its distribution between radioisotopes remains one of the key uncertainties in the understanding of the consequences of the Fukushima Dai-Ichi accident. Inverse modeling methods have already proved to be efficient to estimate accidental releases. This paper presents a new inverse modeling approach to assess the source term by using gamma dose rate monitoring. The approach is applied to the Fukushima accident. The reliability of the retrieved source term is estimated by using model to data comparison and yields a good agreement. An important outcome on this study is its applicability during a response to an emergency situation.
