Tens of thousands of people here in the U.S. have not died from radiation pouring out of Fukushima, as the writer of this boilerplate insists.
If you’re really that concerned, I suggest you purchase your own dosimeter. Here’s link:
This little device will allow to see how much radiation exposure you experience. Maybe you’ll feel better.
I just checked out Ebay - they have lots of dosimeters for sale, and at much lower prices than the link I supplied.
This is no joke. If you are truly concerned about your safety, the price for one of these is small and can bring you peace of mind.
