A tiny amount of radiation from the Fukushima Plant in Japan has been found in Colorado. The amount is almost infinitesimal.

State health leaders say there is no risk to anyone.

A radiation monitor in the Denver-area, one of three in the state, has detected miniscule levels of a radioactive isotope. The monitor has never detected that particular isotope in the several years it has been up and running. That is how they know the radiation is linked to Japan.

"The miniscule amounts measured are approximately 100,000 times less exposure than they would get through typical background radiation in rocks, sunlight, things like that, so there really is no risk to the public," Mark Salley with Colorado Department of Public Health said.

There is a toll-free telephone number set up for Colorado residents who have questions. Call 1-877-462-2911.
