The Environmental Protection Agency reports that a March 25, 2011 sample of milk produced near Spokane, Washington contained a 0.8 pico curies per literlevel of iodine-131.,
The amount of radiation was less than one five-thousandth of the safety guideline set by the U.S. Food and Drug Administration. “These findings are a minuscule amount compared to what people experience every day,” the agency said. A person would be exposed to low levels of radiation on a round trip cross country flight, watching television, and even from construction materials,” Patricia Hansen, an FDA senior scientist, said in a written statement distributed by the EPA late Wednesday.
Iodine-131 has a half-life of about eight days.
The EPA reports that the agency isn’t certain that the radiation source is the Fukushima nuclear plant radiation.
As of Thursday morning (March 31, 2011), beta gross count rate that measure radiation from all radionuclides that emit beta particles “have been thousands of times below any conservative level of concern,” according to the EPA.
Also, as of Thursday morning (March 31, 2011), beta gross gamma measure radiation from all radionuclides that emit gamma rays “have been thousands of times below any conservative level of concern,” according to the EPA.
