A large volume of disaster wastes such as concrete waste, scrap metal, wood waste and so on, in the environment due to the accident at the Fukushima Nuclear Power Plant has been contaminated by radioactive cesium (Cs and Cs). A large challenge has been how to handle the large volume of contaminated material. One strategy for addressing this issue would be the reuse of material from the viewpoint of both effective utilization of resources and the amount of reduction of the contaminants. This paper shows that the outline of dose estimation for some kinds of reuse applications to derive the radioactive cesium concentration in reusable materials.
