The Great East Japan Earthquake on March 11, 2011 generated a series of large tsunami waves that resulted serious damage to the Fukushima Daiichi nuclear power plant and radioactive materials were discharged to the environment. Remediation of contaminated environments is of important issue for the Fukushima residents, and Japanese government established legal framework for decontamination. Before the implementation of full scale decontamination, the Cabinet Office commissioned “Decontamination Pilot Project” to Japan Atomic Energy Agency. The purpose of the project is to acquire technical data and knowledge, and provide integrated expertise for full scale decontamination. In the process of the project, radiation protection of workers for remediation activities was demonstrated. External dose was controlled by daily dose check, and internal dose by protective equipment, whole body counting and screening system under the radiation protection plan.
