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.

It's always the same thing: for decades they tell us that there is no problem with radiation from x-ray equipment or other sources because the doses are so minuscule and so infrequent that it would be like.... Then they come up with some hoary example, such as "a 42-minute walk outside," an example I will get back to in a moment. Decades later, after millions of gullible or option-less people have been exposed to it on a regular basis, a new study comes out linking that very type of radiation and those very doses to some nasty disease.

It happened again—with Dental x-rays and risk of meningioma, a study published today in the American Cancer Society's online journal Cancer. Meningioma is the most common tumor in the brain and central nervous system, representing 33.8% of all brain tumors in the US adult population. The tumor is “associated with neurologic complications” that may include memory loss, hearing loss, vision problems, seizures, and weakness in arms and legs. According to the study, "The primary environmental risk factor consistently identified for meningioma is exposure to ionizing radiation."
