What is the situation with radiation in japan?

Question:

I want to go to japan but is there anywhere unaffected by radiation? is it safe to go to japan? I don't want to get radiation poisoning.

Answer:

You will probably be alright.

This being said the power station is still emitting radioactivity and it does not 'wear off' as Newguinea quaintly puts it. It will take another 30 years for the caesium-137 (which is the main problem) to halve in potency and 88 years for the plutonium-238. Luckily, however, we now have a new Prime Minister and suddenly everything is okay and people can go back to their homes near the power plant.
