Officials from Nevada, California, Hawaii, Colorado, Massachusetts and Washington state, are reporting small levels of radiation that can be traced to Japan have been detected.
Iceland officials are reporting the same thing.
A monitoring station near the Las Vegas Atomic Testing Museum, reported iodine-131 and xenon-133. University of Nevada reported cesium-137 between March 17 and 21.
Public health officials in Massachusetts detected iodine-131 in rain water. Officials in California and Washington state also confirm iodine-131 in rain.
In Iceland officials say that, so far, the radiation levels detected there are less than after the 1986 Chernobyl disaster. They made that statement on March 23. Now there is evidence that plutonium is leaking from the Fukushima Daiichi plant.
