Whether security scanners at airports

The fact there are X-ray and microwave scanners installed at airports, the risk to your health.

For many years at airports to detect passengers concealed weapons used metal detectors. This easy to use device was safe, but had one serious drawback: it can not detect non-metallic objects that pose a threat. So now screening at airports is carried out by means of other technologies.

X-ray scanner

Backscatter x-ray shows a full body image. controversy about the safety of using this scanner under way between experts.

It is believed that X-ray scanners, may serve as a source of dangerous dose radiation. "Through this device a person is exposed to radiation, equal to about 10% of what he received during chest X-ray, "- says John Sedat (John Sedat), professor of biophysics at UC University.

Professor of Biophysical radiology at Columbia University Medical Center David Brenner (David Brenner) confirms: "There is very little risk that the effects of X-rays can cause cancer diseases. "

European authorities almost immediately after the introduction of banned technology

millimeter wave scanner

Millimeter wave scanner takes an image with the help of radio waves. This scanner to stand without shoes and with his hands behind his head. Experts say that these devices are safe for human health.

Andrew Maidment (Andrew Maidment), Associate Professor, Department of Radiology, University of Pennsylvania, explains, that devices that emit radio waves that are harmful only when the result to molecular changes. Millimeter wave scanner at the airport on this, fortunately, is not capable.

"I participated in a study that tested the effect of irradiation on this scanner pregnant, potentially pregnant women and newborns. And I can say with confidence that it is safe. I'm not afraid for himself, his wife and children when we pass through the scanner, "- says Maidment.

Even if you often fly on airplanes, you get a tiny dose of radiation, which does not harm your health.
