AW: [ RadSafe ] Myth or Fact?

In Europe a skilled dentist (or his technician) with state-of-the-art equipment will expose you to about 0.01 mSv effective dose per examination. 

At sea level you get about 3 mSv natural radiation where the bulk of 2 mSv comes from exposure to radon, in Denver you may get more than 3.6 mSv and in Cornwall or other areas of high natural background radiation this can approach 10 mSv - per year.

So depending where you live that ratio will vary between 300 and 1000 and any attempt to associate these increased exposures with health detriments failed so far - suggestive evidence pointing even towards the opposite, i.e., improvements.

Best regards, Rainer

Betreff: [ 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.
