How long will it take until I can go again to Japan without being worried for radiation?

Question:

I'm talking about going to Tokyo, Gunma, Nagano, Shizuoka and Yamanashi not up to the North, more around the Kanto.

What do you think???

And if I mean no worry then I mean no radiation danger in this area (like tape water free of radiation, air free of radiation, no danger with the crops that grow there)

Thanks

Answer:

I am next to Shizuoka now. It is safe. Radiation levels are at normal background levels. As long as you stay 30 miles or more the power plants, you are fine. Currently they will not let get that close if you wanted to.

Even the tap water thing was overblown in the media. It was a little higher then normal for tap water in Japan, but still within safe levels overall. One place closer to Fukushima had 1 reading that went above a level for infants for about 1 day.

Japan has stopped the crops from the effected area, food is safe here.

There is no such thing as "air free of radiation." However, you are currently getting more radiation from your monitor reading this answer then you will from the air in Tokyo.

++++++++
Here are some numbers from a non-TEPCO dosimeter.

Background radiation in Tokyo is usually about .025 m/Rem per hour.
Even when we were under the plume event that rate rised to only .05 m/Rem per hour.
For comparison, you get about 4.0 m/Rem flying from New York to LA.
You get about 10.0 m/Rem from an X-Ray.
So as you fly from where ever you are to Japan, you will get far more radiation then there is in Tokyo.
So don't worry about people like Pzifiiishh, they are just spreading panic to further their anti-government, anti-nuclear energy agenda.
