OOPS!  Left out a few words.

360 mRem / year is a valid figure for natural background, and a dental
x-ray is about 1 mRem effective dose to the thyroid, depending on type.
(Skin dose is substantially higher)

Subject: [ RadSafe ] Myth or Fact?

Hello Radsafers,

    I recently read a book called "Myths, Lies, and Downright Stupidity"
by John Stossel of 20/20 fame. In it he makes a case for food
irradiation, which was refreshing to hear from a member of the media.

 Everything was going fine until I got to the part where he states
"Every year, the average U.S. citizen is exposed to natural radiation
equal to about 360 dental X-rays."

Now, I'm certainly no expert on this, but that figure does seem pretty
high to me. So, I'll ask the experts, (you folks), what you think. Myth
or fact? I'm curious.
