*Figures for MiyagiPrefecture are measured by transportable monitoring post.Moreover, 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.The data of Fukushima Prefecture published the one that had been obtained by 19 o'clock of today.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 1MGy/h=l1g Sv/h.*The table was made by MEXT, ased 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 for Miyagi refecture are measured by transportable monitoring post.Moreover, 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.*InFukushima Prefecture, the monitoring post in Futaba-gun is located at an evacuated area, since it is difficult to measure,

figures were measured in Mombiyama (Fukushima City) as an alternative.The data of Fukushima Prefecture published the one that had been obtained by 19 o'clock of today.o 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 1MGy/h=l g Sv/h.*The table was made by MEXT, ased 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.
