Traces of radiation from the nuclear disaster in Japan have been detected in Arizona, officials said.
Tiny amounts of Iodine-131 radioactive material associated with releases from the Fukushima Daiichi power plant were detected over the weekend by the Arizona Radiation Regulatory Agency.
The radiation is at low levels, and does not pose a health risk, the agency said in a press release Monday.
The radiation was picked up by sensors located in Phoenix and west of the Valley.
“The average background radiation can range from 100-300 millirems per year," said Aubrey Godwin, ARRA director. “The amount of additional radiation we are seeing in Arizona is less than 0.1 millirem. Such low concentrations of Iodine-131 do not pose a public health threat to Arizonans.”
Potassium iodide (KI) pills should not be taken as a precaution.
"Arizonans who take KI unnecessarily could place themselves in danger of negative side effects, including severe allergic reactions, abnormal heart rhythms and nausea," the agency said.
