Is it good for your health to do security check at the airport?

In order to strengthen security, more and more airports are installing new X-ray scanners. Although it has caused great controversy in personal privacy, in terms of health hazards, according to a recent study published in the Archives of Internal Medicine, the radiation of this scanner will not bring obvious harm to the human body.

Although this whole-body scanner will emit ion rays, its dose is equivalent to 1/50 of the usual dental X-ray examination and one thousandth of the chest X-ray examination. If/kloc-0,000,000 people fly/kloc-0,000 times a week for one year, then the X-ray scanning of airport security will cause about 4 people to get cancer, which is far lower than the number of people suffering from cancer caused by receiving high-altitude rays during the flight (about 600 people).

Therefore, we don't have to worry too much about the possible health hazards caused by X-ray scanning in airport security inspection.
