Abstract
The Tohoku District-off the Pacific Ocean Earthquake and the resulting tsunami generated a huge amount of disaster wastes on March 11, 2011. After that, radioactive materials were discharged into the environment by the severe accident at Fukushima Daiichi NPS of TEPCO and some of the waste was contaminated. Furthermore, a large amount of contaminated soil and materials will be generated by future decontamination activities. In this paper, the current situation of radioactive contaminated wastes, the strategy of handling them, the guideline for transporting the waste will be explained. JNES investigated radiation exposures of people from living activities and restoration activities for the disaster upon requests from the LNERH. They include contamination of a car running on the contaminated land, an investigation of methods to measure radioactivity of massive wastes quickly and exposure of worker involving restoration activity for railroad. Results of those investigations will be also briefly described in this paper.
