Oh for crying out loud people, stop buying friggin radiation pills. How many times do I have to say it, the disaster is in Japan, not America or Canada. Health agencies in California and Canada are warning people to stop buying potassium iodide as it’s “not a radiation antidote in general.” The fear that radiation could reach their shores and the fact no one believes a word any government says, has caused a mini-panic. One company has already sold out of 10,000 14 pill packs. Anywho, before you rush off to join the panic, the tablets are solely designed to shield the thyroids from radioactive iodine. In other words IT BLOCKS NO OTHER TYPE OF RADIATION NOR PROTECTS ANY OTHER BODY PART. Oh and if you are over 40 you’re screwed, it won’t help ya! So if you are that concerned I suggest you ring up any old nuclear power plant near you and ask if they have any spare radiation suits.
