As far as the air dose rates are concerned in the MEXT’s announcement, Kanagawa, Saitama, Chiba, Gunma and Tochigi are almost the same as Tokyo. The radiation dose in the air in Ibaraki has been slightly above 66 micro Sv after March 15, if you add up the doses announced by the MEXT and then subtract the average dose in normal times (in the case of staying outdoors for 8 hours a day). Thus, it is fine to lead a normal life as you usually do.
