Doctors appear to be causing tens of thousands of cancers with CT scans
and dentists may be causing a few brain tumors with dental X-rays (see
my last two videos
Cancer Risk from CT Scan Radiation and
Do Dental X-Rays Cause Brain Tumors?),
but what about these new-fangled airport full-body scanners that use
so-called backscatter technology to reduce X-ray exposure? A thousand
times less radiation exposure than a chest X-ray, though they’re still
being phased out. In fact, flight passengers may get
100 times
more radiation during the flight every hour, because they’re so high up
in the atmosphere and exposed to more cosmic rays. Does that mean a
round-trip cross-country flight is almost like getting a chest X-ray?
Yes. Anyone who’s seen my
speaking schedule knows I’m totally screwed. But what can you do? As is the answer to so many health questions, you can eat healthily.
