Q:
Tim--do you know how wide an area is affected by the various disaster ratings for nuclear incidents? With the Japan incident now upgraded to Level 5, how many square miles are we talking about here?

The only safe way to handle radiation is 1. Distance 2. protection 3. time. Since the life of radiation is enormous, time is not much of an answer. The type of radiation determines what protection is needed (I.E. Gamma rays etc) The best way to create distance is to go upwind. Radiation is carried in dust (fallout). The distance required, even upwind is determined by the massiveness of the explosion in the case of a atomic blast and the chance of winds changing. As a side note, The U.S. government’s Department of Health and Human Services has approved potassium iodide (KI), in a dose of 130 milligrams (mg), as a thyroid blocking agent in radiation emergencies.

Thanks, Tim. Still pretty scary.

Thanks for your question Smitty. Since the danger zone around Fukushima moved from 20 kilometers to 30 K, we are looking at a 37 mile circle around the power plant, which contains roughly 1,900 square miles. On the INES scale, this event is currently coming in at about the same damage level as Three Mile Island in 1979.

Thanks, Santa. Anybody else know about how wide an area is affected by this?

I am totally ignorant on nuclear dangers, but I understand from the news that there are basically eight levels on the INES scale to worry about. The actual area of radiation will not be nearly as big as the areas that will be affected by water run off and other such factors. So how big of an area is hard to predict at this point. As I said I am igorant of the whole thing and those are the things I have gotten from the news. I am basically a mushroom and you know what they get feed and that are always kept in the dark as much as possible.
