Colorado officials have detected miniscule radiation levels in the state from Japans Fukushima nuclear power plant, according to a news release from the Colorado Department of Public Health and Environment.
Chris Urbina, chief medical officer and executive director of the agency, said the radiation does not pose a threat to public health.
Radiation can be detected at levels millions of times lower than the level that would cause health impacts, Urbina said in the news release. Radiation levels detected in Colorado are consistent with those reported for other states.
Monitors in California, the first state to report radiation detection, sensed radioactive particles five days ago.
The Fukushima plumes radiation diluted significantly in its journey across the Pacific Ocean, the release said.
Urbina said there is no need for people to take potassium iodide tablets, used to prevent radiation damage to the thyroid.
Unnecessary use of the tablets could cause a variety of adverse reactions.
Americans receive doses of radiation from natural sources like the sun that are about 100,000 times higher than what was detected coming from Japan, the release said.
