The US ships found these radiation readings before the actual belief of severe air contamination. It is believed that two of the site reactors have begun partial meltdown. The lack of cool down of the reactors is the fear, and even worse one of the sites is believed to have been fully exposed to the outside air. The Japanese Government is not denying this. Why? Because the actual site is not owned by the government but a contract company similar to Alabama Power. The same company that has been in question several times in the past about nuclear incidents. The hope here is that they can get power back to the back-up safety generators. Is it too late? Here is the deal, this will not effect any other country except Japan and maybe Russia; in a health standpoint that is.
