A Run on Potassium Iodide


Japan's nuclear problems are causing "anxiety" in the US as consumers and some businesses rush to buy potassium iodide, a treatment to protect against radiation-induced thyroid cancer, reports The New York Times' Andrew Pollack. Some companies in the US are buying the drug to send to their employees in Japan, and Japanese officials are distributing iodide tablets to evacuation centers near the nuclear plants that are leaking radiation, Pollack says. But for Americans who are not in Japan and have no intention of going there, doctors say the pills are unnecessary, he adds, as there is more than enough of a safe distance between Japan and the US's west coast.
