japan nuclear Econintersect:  The first traces of radiation from the nuclear plant disaster in Japan have reached the U.S. east coast.  Detectable traces of radiation have been reported by the major electrical companies in the southestern U.S., Progress Energy, Duke Energy and Scana Corp.

The amounts of radiation detected so far are very small.  The electric companies will be conducting continuing monitoring going forward.

From the Raleigh News & Observer:

The amounts detected so far are minuscule and pose no public health risks, nuclear experts and health officials said Sunday. A roundtrip international airline flight exposes a person to 100,000 times as much radiation, according to the U.S. Environmental Protection Agency.

"You could continue to receive that kind of dosage and not accumulate anything because it's so small," said Brian McFeaters, disaster preparedness coordinator for Wake County Human Services.

Last week Raleigh-based Progress Energy said it picked up very low levels of iodine-131, a radioactive byproduct of nuclear fission, at its Robinson nuclear plant in South Carolina and at the Crystal River plant in Florida.

The company expects to pick up similar readings this week when it takes periodic tests at the Shearon Harris nuclear plant in Wake County and the Brunswick plant near Wilmington, Progress spokesman Drew Elliot said.

The samples detected on the East Coast traveled half-way around the planet from Japan since several reactors were disabled by a tsunami March 11.

Elliot said the radioactive traces are not from Progress nuclear plants, because they were measured in isolation without the presence of other isotopes that would be present if the radioactive release took place locally.

"It's just above the threshold of detectability in our very sensitive measuring devices," Elliot said.
