No Health Risk to Passengers from Airport Scanners

ScannersAccording to a study by U. S. researchers, it has been established that the radiation exposure from airport scanners is very low.

Dr. Rebecca Smith-Bindman, a Radiology Professor at the University of California, San Francisco, said, "There is such a vast difference between super-low doses of radiation and the really high doses that happen if you are in the middle of a nuclear accident".

Smith-Bindman said that the proper use of the machines tremendously brings down the exposure level. She also said that the risk from airport scanners is very low.

Smith-Bindman said that mistakenly, we put all the radiations in the same category. She explained that nuclear crisis in Japan has increased the fear about radiation; though to get more radiation exposure a person needs to get
50 airport scans, as one gets from a dental X-ray.

Travelers and airline crew have shown their concerns about the repeated use of body scanners, which are used by the Transport Security Administration to identify banned items.

The Backscatter X-ray machine, a full-body airport scanner, exposes people individually to unused radiations; it is also used in common medical X-ray.

The travelers were divided into three groups to estimate the risk from these radiations, all flyers, frequent fliers and 5-year-old girls who are frequent fliers, as kids get affected very easily.

Smith- Bindman said that to equalize the dose of one CT scan, one has to go through an airport scanner 200,000 times.
