FTA: "Some radiation was released when the pressure vessel was vented. All radioactive isotopes from the activated steam have gone (decayed). A very small amount of Cesium was released, as well as Iodine. If you were sitting on top of the plants’ chimney when they were venting, you should probably give up smoking to return to your former life expectancy. The Cesium and Iodine isotopes were carried out to the sea and will never be seen again."

And my main point is not that i want to set the japanese accident on the same level as chernobyl, but more to make clear that nobody expected such a strong contamination after 25 years thousands of miles away from the center of explosion. World is not behaving linearly, even though some people want us to believe it does.
