内容記述 |
More than a decade after the Fukushima Daiichi Nuclear Power Plant (FDNPP) accident, concerns about radiation exposure persist among residents in areas that were contaminated. Eastern Fukushima includes municipalities located on the Abukuma Highlands, a region with elevated levels of naturally occurring radionuclides in granitoid formations. As a result, residents in some areas near the FDNPP may be exposed to both natural and artificial radionuclides. This study aimed to assess radiation doses from internal exposure to natural and artificial radionuclides via inhalation. Radon and thoron progeny concentrations were measured over one year (2022−2023) in 69 dwellings and buildings near the FDNPP and 30 locations in other regions of Japan. Atmospheric radiocaesium (137Cs) concentrations were also monitored in three Fukushima municipalities. Annual effective doses from inhalation were estimated using dose coefficients for each radionuclide. The annual effective dose from natural radionuclides reached up to 0.90 mSv, exceeding the national average for the Japanese population (0.59 mSv), mainly due to higher thoron progeny concentrations. In contrast, the dose from inhaled 137Cs was much lower, estimated at 5.2 × 10−6 mSv—about five orders of magnitude less than that from natural sources. A temporary increase in atmospheric 137Cs concentration was observed, likely caused by the resuspension of particles during nearby demolition activities. This study provides a comprehensive assessment of inhalation doses from natural and 137Cs, offering valuable insights for radiation risk communication in the post-emergency phase. |
