(WASHINGTON) -- The damage at the Fukushima Daiichi nuclear power plant in Japan has had a residual effect felt all the way in the U.S., with rainwater here showing trace amounts of radiation.
It seems that the very lightly contaminated rain is turning up coast-to-coast, with radiation showing up in Nevada and other Western states and as far East as North Carolina, South Carolina, Pennsylvania and Massachusetts.
One of the radioactive by-products found in U.S. rain is in iodine-131, which briefly caused Japan to institute a ban on tap water in Tokyo and other prefectures. However, there are no such worries here, according to the Environmental Protection Agency.
In fact, the risk to the public is so low that the EPA says that Americans are exposed to far more radiation when they take an international airline flight.
