Examination of external radiation exposure assessment method of plant incineration workers with electronic dosimeter in disaster area

A large amount of radioactive materials were emitted by the Fukushima Daiichi Nuclear Power Plant accident that was caused by the Great East Japan Earthquake. Decontamination work has been continued to reduce the radioactive contamination in disaster area. The amount of decontamination waste is very large, and the volume is needed to be reduced by incineration process. Therefore, the assessment of radiation exposure level in incineration plants are indispensable. In this research, assessment of external exposure of plant workers was carried out by measuring air dose rate and integral dose of working environment with NaI scintillator and electronic dosimeters.
