Measurement Results of Air Dose Rates Nationwide and in Fukushima Prefecture (Real-time Distribution) Daily Average ( From April 2018 to August 2018 )
- This data was created based on the results of "Measurement Results of Air Dose Rates Nationwide and in Fukushima Prefecture (Real-time Distribution)" released to the public in the Monitoring Information of Environmental Radioactivity Level portal site by the Secretariat of the Nuclear Regulation Authority.
- Although both fixed mount type monitoring posts and portable monitoring posts measure absorbed dose rates [μGy/h] (micro Gray per hour), the data of monitoring posts are released to the public as effective doses with unit of μSv/h (micro Sievert per hour) using the conversion defined by the Guideline for Environmental Radiation Monitoring (Nuclear Safety Commission): 1 μGy/h (micro Gray per hour) = 1μSv/h (micro Sievert per hour). On the other hand, ordinary survey meters and the Real-time radiation measurement systems installed in Fukushima Prefecture measure the 1 cm dose equivalent rate [μSv/h] (micro Sievert per hour). Usually, The 1 cm dose equivalent shows a higher value than the effective dose nevertheless both units are [μSv] (micro Sievert).
