A new report released by a UC San Francisco radiology specialist has claimed that airport scanners emit low levels of radiations and do not pose any significant health risk to people. The study is expected to calm the fear of passengers who undergo these scans.

More than 500 scanners at 78 airports were installed by the U. S. Transportation Security Administration. Around half of the scanners use X-rays, while the rest use radio waves to create images. The report has advised the passengers not to fear going through the full-body scan for health reasons because the risk associated with the scans is very small.

The report has suggested that the scanners use low levels of radiation to create a image which looks like a nude image. The image helps the authorities to detect weapons or contraband hidden under clothes.

Dr. Stephen Machnicki of Lenox Hill Hospital in New York said that the level of radiation from these scanners is less than the level of radiation during a cross-country flight. Flying at higher altitudes exposes the people to ionizing radiations which can be risky.
