This is indeed a company selling Potasidol. They are just a company trying to sell something by playing on peoples fears. But before you run out and buy it consider this from the Washinton Post and other news sources.
(In part)...the U.S. Nuclear Regulatory Commission (NRC) said it is unlikely that harmful levels of radiation leaking from Japanese reactors will reach any part of the U.S., including Hawaii, Alaska, and various territories in the Pacific, considering the vast distances between Japan and those areas.

The story also refers to the opinion of Dr. James Thrall, radiologist-in-chief at Massachusetts General Hospital in Boston and president of the American College of Radiology, who said the chances of consequential radiation exposure from Japan anywhere in the U.S. are ?essentially zero.?

So we have atmospheric scientists, the government and a leading medical official on the same page that U.S. residents have little cause to worry about nuclear radiation based on the current circumstances.

So make your own choice.
