radiation

An oceanography institute announced Monday that trace amounts of radioactivity from Japan have been detected off the West Coast.

Radiation experts say the low levels of radioactivity measured do not pose a health threat here.

If you see an unusually low-flying helicopter cruising above Seattle or Bellevue, don't worry. It’s just a project of the State Department of Health to measure naturally occurring radiation in King and Pierce Counties.

Washington milk is safe

Worried about radiation from Japan contaminating milk here at home? The Washington state departments of Agriculture and Health say the latest tests show no sign of any radioactivity in milk sampled in Tacoma and Spokane.

Last week, the EPA announced that trace amounts of radioactive Iodine-131 were detected in a sample from Spokane, but at levels 5,000 times below anything that would be remotely dangerous. Officials say drinking a pint of milk with radiation levels that low would amount to less than half of the exposure you would get in a five hour plane flight.

The small amounts of radioactive Iodine-131 found in milk in Spokane has been causing ripples of concern throughout the Northwest. Officials say the tiny amounts of radiation found in the milk were probably blown over from Japan’s stricken nuclear plants.

Just outside the Tri-Cities, Drex Gauntt’s alfalfa fields roll out like a plush emerald shag carpet. One of the ways that cows can pass Iodine-131 into their milk is by eating grass or hay that’s been contaminated with the radioactive isotope. Gauntt says he’s not too concerned.
