At this point I suggest the folks in Northern Hemisphere to get a good command of the following simulation and follow it in the next days.

(On that map, Japan is on the left side, in the vertical middle. You need to configure the animation - select 4 days, 6 hrs, click Build animation, and then it's good to pause it and animate manually by clicking Next.)
When the winds from Japan reach you, stay indoors for a week or two if you can afford it, or at least AVOID RAIN, and you may avoid serious trouble, including cancer.
And PLEASE don't rely on mass media or governments to tell you the truth.
Investigate, just how HORRIFIC the Chernobyl fallout was. Link here: [link to en.wikipedia.org]
If you see radiation warning for you country then that's fine, but if you don't see it, do not assume the air is clear.

In addition to that, we advise the readers to store at least minimum Potassium Iodide tablets, or Iodine tincture. It is said the tablets to be better, but in the absence of them, the iodine solution with water and alcohol (tincture) is also working, 5 drops of 2% tincture per liter. It is used for disinfection of water even without radiation. The purpose is to prevent the poisoning with the radioactive iodine that will be /is released by the reactors, by taking the non-radioactive iodine.
