There is no current threat to public safety, said Progress Energy spokesman Drew Elliot.
Monitors at Progress Energy's nuclear plants in Hartsville, South Carolina, and Crystal River, Florida, picked up low levels of radioactive iodine-131. So did Duke Energy's monitors at its two nuclear facilities in South Carolina and the plant in Huntersville, North Carolina.
Mr Elliot said: 'If there were radiation coming from one our own sites, we would be seeing other types of radiation than iodine-131.
The Obama administration is sending a squad of robots to Japan to help efforts to regain control over the Fukushima nuclear plant.
"A shipment is being readied," Peter Lyons, who oversees nuclear power in the department of energy, told a Senate committee. "The government of Japan is very, very interested in the capabilities that could be brought to bear from this country."
The news came as the Japanese government said it was considering nationalizing the operator of the crippled power plant at the center of the worst nuclear accident in the country's history, amid mounting criticism of its handling of the crisis.
"Our preparedness was not sufficient," government spokesman Yukio Edano said. He said that when the current crisis was over they would examine the accident closely and thoroughly review safety standards.
Reports from Reuters and the Associated Press indicate that radiation from Japan nuclear facilities has reached the US West coast, but that radiation is “minuscule” and contains “very low” levels.
While we want to believe that the recent panic over Potassium Iodide has been overblown, we have yet to see any official radiation numbers from the US government. It is clear that radiation in the fallout area around the nuclear reactors at Fukushima is dangerous and high enough to kill those in the direct vicinity of the meltdown. What’s not clear is how much radiation is being released at ground zero, and how that radiation has dissipated as it spreads out in Japan and across the Pacific on its way to the west coast of North America.
According to the United Nations’ official radiation fallout forecast, radiation that does reach the US west coast will be “diluted”.
The Japanese people are demonstrating a true allegiance to social order and calm as they search for loved ones or wait in lines for basic necessities. There is not a hint of looting or violence, even as residents must wait in line for 12 hours to buy food. Everyone remains calm and polite, earning the admiration of the world.
"Supermarkets are cutting prices and vending machine owners giving out free drinks as people work together to survive," remarked a writer in the Telegraph, as he wondered why we saw looting in disasters past, but not in Japan.
There were also reports of citizens voluntarily turning their lights and appliances off, so as to save energy for the rest of the population.
The US training manual for Fire Fighters is called ‘Fire Officers Guide to Disaster Control’. The 600 page book covers all forms of emergency situations including Fires and natural disasters. However Chapter 13 is titled ‘Enemy Attack and UFO Potential’.
The chapter lists a range of possible scenarios that a Fire Officer may experience in a potential UFO invasion. For example, the manual states:
