*Figures for Miyagi Prefecture are measured by transportable monitoring postMoreover, the value of the fixed mount type monitoring post set up in Sendai City is described about the range of the value ordinary of the past.*In Fukushima Prefecture, the monitoring post in Futaba-gun is located at an evacuated area, since it is difficult to measure,

figures were measured in Momijiyama (Fukushima City) as an alternative.* In Shimane Prefecture, readings are measured by alternative machine from 5pm on April 4 because of setting up the equipment*These figures are estimated as 1 j Gy/h=tl Sv/h.*The table was made by MEXT, based on the reports from prefectures.*Usual value band means a range of the maximum and minimum value observed before the earthquake.*The data, usual value band of Gunma Pref.,Yamanashi Pref. and Kouchi Pref., are corrected from theversion released on April 9 19:00.

figures were measured in Momuiiyama (Fukushima City) as an alternative.* In Shimane Prefecture, readings are measured by alternative machine from 5pm on April 4*These figures are estimated as 1 Gy/h=l p Sv/h.*The table was made by MEXT, based on the reports from prefectures.*Usual value band means a range of the maximum and minimum value observed before the earthquake.*The data, usual value band of Gunma Pref.,Yamanashi Pref. and Kouchi Pref., are corrected from theversion released on April 9 19:00.
