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.
As Anna King reports Eastern Washington has a long history with radiation.
Just outside the Tri-Cities, Washington, 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. But Gauntt says he's not too concerned.
Experts say there's not enough of it to be a health risk. He says what worries him more is Japan's economy.
Drex Gauntt: "But exporters are telling us that the need for feed is still there. This hasn't stopped any of the requests they've had for orders of forage."
Still dairy and alfalfa farmers like Gauntt worry about consumer perceptions.
Michael Payne is a research veterinarian at U.C. Davis. He says people should be more worried about proper pasteurization and packaging of milk products than radioactive Iodine-131 from Japan.
Michael Payne: "As God as my witness I would drink that milk sample that came out of Spokane. I am that unconcerned about that level of radioactivity. I really am."
But historically large releases of Iodine-131 caused health problems in the Northwest.
About 250 people who lived mostly north of Richland, Washington claim they were exposed to radiation from the Hanford Nuclear Reservation.
The Downwinders as they are known are still suing the federal government. One of their attorneys is Brian Depew.
Brian Depew: "So maybe the unanticipated events of Japan is that these people will get a chance to be heard and that's all they want."
Two months ago about thirty of Depew's clients diagnosed with thyroid cancer were offered a settlement of $10,000 each from the federal government. He says most of them turned down the offer.
