And these traces of radiation from Japan as just the first amount emitted from that nuclear plant…wait til the radiation gets here from the meltdowns.

Radiation from Fukushima plant detected in Sacramento, EPA says

A minuscule amount of radiation from the stricken Fukushima Daiichi nuclear reactor in Japan was detected in Sacramento but at such a low level that it posed no threat to human health, the U.S. Environmental Protection Agency said Friday afternoon.

One station in Sacramento detected “minuscule quantities” of a radioactive isotope, xenon-133, that scientists said they believed came from the reactors at the stricken Fukushima plant.

But the level detected would result in a “dose rate approximately one-millionth of the dose rate that a person normally receives from rocks, bricks, the sun and other natural sources,” according to an EPA statement.

Xenon-133 is a radioactive gas created during nuclear fission.

The detection of the xenon-133 came from a radiation monitoring system run by the U.S. Department of Energy able to “detect tiny quantities of radioisotopes that might indicate an underground nuclear test on the other side of the world,” the statement said. “These detectors are extremely sensitive and can detect minute amounts of radioactive materials.”

A separate detection system run by the EPA, known as RadNet, also has shown no harmful levels of radiation coming to the United States. The system was developed in the 1950s during the Cold War.
