| 内容記述 | Mt. Fuji is located approximately 300 km southwest of the Fukushima Daiichi Nuclear Power Stations. We performed the radiation survey along two main Mt. Fuji's trails from 4:30 to 18:30 on July 9, 2011. We climbed the Yoshida trail from the Fuji-Subaru Line fifth station (2,300 m in altitude) to the Yoshida-Subashiri top (3,720 m in altitude) and descended the Subashiri trail from the Yoshida-Subashiri top to the Subashiri new fifth station (2,000 m in altitude) on foot while measuring gamma rays. The dose rate 1 m above ground measured using a NaI (Tl) scintillation survey meter were within the range from 0.03 µSv/h to 0.05 µSv/h throughout our measuring trip. We used a NaI (Tl) scintillation spectrometer for gamma-ray pulse height spectra measurement. The gamma-ray pulse height spectra obtained at least 2,500 m in altitude on both of the Yoshida and Subashiri trail showed the peaks of two radioactive cesium isotopes (Cs-134 and Cs-137) and natural radioactive nuclides. It was confirmed that a radioactive plume released from the Fukushima Daiichi Nuclear Power Stations had arrived at least 2,400m above sea level of Mt. Fuji. | |||||
