Avoid radiation “backscatter” airport scanning

There are two types of scanners. The millimetre wave machine (left)  is safe, creating an image of the body by using electromagnetic waves. The other, “backscatter” devices, )right) use low-energy X-rays to produce a picture of the body. These are not so safe…………

Doctor advises travellers to avoid being X-rayed Pat-downs far healthier choice, The Vancouver Sun,  By Dr. W. Gifford Jones, Special to the Windsor Star January 6, 2011 The U.S. is replacing many metal detectors with more sophisticated equipment, better described as personal exposure devices. In effect, the technology can detect articles beneath the clothing along with you-know-what — and this infuriates many travellers.

There are two types of scanners. The millimetre wave machine is safe, creating an image of the body by using electromagnetic waves. The other, “backscatter” devices, use low-energy X-rays to produce a picture of the body. These are not so safe…………

As you might expect, the U.S. government says that the amount of radiation exposure is minimal. It claims the amount the body receives is the same as natural radiation exposure from two minutes of flying. But some authorities believe the radiation dose is higher.

Experts say backscatter machines use low-energy X-rays. This means that “MOST” of the radiation is absorbed by the skin and, unlike medical X-rays, does not enter the body. This does not reassure me one bit. And since it’s absorbed by the skin, will it cause skin cancer years from now?…….My advice is to forget Victorian modesty. Rather, avoid radiation like the plague. Remember: a small hole can sink a large ship. Too many bits of a “little radiation” can produce long-term health risks. Take the pat-down every time.
