Sales of iodine pills have soared in the United States amidst concerns of radiation fallout from Japan's nuclear crisis. From the Guardian:

The fires and explosions at Fukushima Daiichi nuclear plant have prompted a massive increase in the sale of anti-radiation tablets in the US and Canada – despite health officials and a prominent UK scientist dismissing it as unnecessary.

Companies in North America have reported selling out of potassium iodide supplements, which can prevent the body absorbing radioactive iodine, while in the UK one chemical manufacturer has reported a "surge" in inquiries about the chemical.
