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.

DESCRIPTION: Based on studies of atomic bomb survivors, Chernobyl victims, and airline pilots exposed to more cosmic rays at high altitudes, fruits and vegetables may decrease radiation-induced chromosome damage.
For more on the cancer risk associated with CAT scans and dental X-rays see my last two videos Cancer Risk from CT Scan Radiation (http://nutritionfacts.org/video/cance...) and Do Dental X-Rays Cause Brain Tumors? (http://nutritionfacts.org/video/do-de...). Wednesday I'll review interventional studies where plant foods are actually put to the test in Reducing Radiation Damage With Ginger And Lemon Balm (http://nutritionfacts.org/video/reduc...).
Those who want to count my chest X-ray equivalents can view my speaking schedule here (http://www.DrGreger.org/dates.html)—just don't tell me!
USDA keeps a nice list (http://fnic.nal.usda.gov/food-composi...) of phytonutrient resources. Cryptoxanthin sources listed here (http://lpi.oregonstate.edu/infocenter...). Healthy Pumpkin Pie (http://nutritionfacts.org/video/healt...) anyone?
Lutein and zeaxanthin can help us Prevent Glaucoma and See 27 Miles Farther (http://nutritionfacts.org/video/preve...). Are these eyesight-saving phytonutrients also found in eggs? You might be surprised: Egg Industry Blind Spot (http://nutritionfacts.org/video/egg-i...).

Why might eggs be harmful even if not radioactive? See Egg Cholesterol in the Diet (http://nutritionfacts.org/video/egg-c...) or my other 57 videos on eggs (http://nutritionfacts.org/topics/eggs/). I cover natural and artificial radioactivity in fish in Fukushima and Radioactivity in Seafood (http://nutritionfacts.org/video/fukus...) and explore concerns about other pollutants in my 89 fish videos (http://nutritionfacts.org/topics/fish/).
