Q: If you ate that, what would it mean?
A: You’d have to eat 2 pounds of the most contaminated spinach to absorb about as much radiation as you’d get from a CT scan of the head, says Dr. Clifford Chao, radiologist-in-chief at New York-Presbyterian Hospital.
People who drank milk with the highest measured levels of iodine for two weeks would absorb less than a year’s worth of natural background radiation, according to a report from British environmental radiation group, Mike Thorne and Associates Ltd. But infants would absorb more than adults.
Q: What about breastfeeding?
A: Radioactive iodine could be in breast milk if nursing mothers in Japan were exposed; potassium iodide comes in doses for infants, too, if needed.
Q: What’s being done to make sure contaminated foods don’t reach consumers outside of Japan?
A: China, South Korea and a number of neighboring Asian countries have ordered radiation monitoring of food imports from Japan.
“There is no risk to the U.S. food supply,” the U.S. Food and Drug Administration said Monday.
Q: How does radiation get into food anyway?
A: Fallout can land on crops in fields and wash into the soil to be soaked through the roots. Livestock can eat contaminated animal feed. It’s possible seafood could be affected from contaminated water, although in the ocean “dilution would be huge,” Mettler says.
Q: What about canned or other foods stored before the earthquake _ can residents eat that?
A: The WHO says radioactivity cannot contaminate sealed packaged foods, and that cropland can be covered with tarps and livestock brought into barns and fed clean feed.
Q: How long will radiation be a food threat?
A: Radioactive iodine decays quickly, with a half-life of eight days, meaning the length of time it takes for half of it to break down harmlessly. “In a couple of months, the iodine is a non-issue,” says Mettler.View Entire Story
