Zero Hedge 
May 27, 2011
So far the only good news to accompany the Fukushima catastrophe has been that for all the fallout, the radiation has been mostly contained due to Northwesterly winds which have been blowing any radioactivity mostly out and into the Pacific (coupled with relatively little rainfall), as well as the dispersion of irradiated cooling water which promptly enters the Pacific after which it is never heard of or seen again (there is at least a several year period before 3 eyed tuna fish feature prominently in restaurants across the country). This may be changing soon now that Super Typhoon Songda, which according to Weather Underground will form shortly as a Category 5 storm with 156+ mph winds, will take a northeasterly direction and 2 days later will pass right above Fukushima. The good news: by the time it passes over Fukushima, Songda will be merely a Tropical storm. The bad news: by the time it passes over Fukushima, Songda will be a Tropical storm. As the latest dispersion projection from ZAMG shows, over the next two days the I-131 plume will be covering all of the mainland. Although judging by how prominent this whole topic is in the MSM lately, it seems that conventional wisdom now agrees with Ann Coulter that radioactivity is actually quite good for you.
