Is it true that the radiation dose in Seoul,Korea is too high?

In Japan, there was an accident at the Fukushima nuclear power plant,so the space radiation dose became higher in the East of Japan. In South Korea, nuclear power plant accident has not been reported.

However, I read some private reports that radiation dose in Seoul is high. http://cutplaza.blogspot.jp/2013/09/radiation-very...

Is it true?

When the dose of radiation was measured in the South Korean soul, the very high dose of radiation was measured.

0.22 uSv per hour of inside of shop.

4.32 uSv per hour which comes outside shop.
