The widespread environment was contaminated by radioactive cesium discharged by the severe accident of the Fukushima Daiichi Nuclear Power Station. Decontamination measures have been implemented extensively, resulting in the generation of large volume of decontamination soil that has been placed in temporary storage. To reduce the volume of decontamination soil, it can be effective to recycle the soil as construction material. This report shows the concept of safety assessment method for recycle to public projects in which the management system and allocation of responsibility are clarified, scenario construction and parameter selection, and also the results of safe assessment for the recycle to coastal levees.

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.
