QHow high are radiation doses in Fukushima Prefecture?
ARadiation air dose rates in the main cities of Fukushima Prefecture are no different from those in Tokyo and other major cities around the world.

Compared to immediately after the accident at the nuclear power station, radiation doses in Fukushima Prefecture have declined due to decontamination efforts and the properties of the radioactive materials (whereby radiation attenuates over time);In the cities of Fukushima Prefecture, where normal life is conducted, radiation doses are no different from those in Tokyo, New York, Seoul and other cities around the world.

Having said that, inside the "difficult-to-return zones", there are still areas where radiation doses are relatively high.
