A team of US researchers has revealed that airport scanners are extremely safe as far as exposure to radiation is concerned.

With a brewing concern over exposure to harmful radiation among the frequent travelers, the team of two doctors, including Rebecca Smith-Bindman and Pratik Mehta of the University of California in San Francisco, claimed that the radiations emitted from the scanners are not as damaging as nuclear radiations.

Referring to the Japan’s nuclear crisis, Dr. Rebecca Smith-Bindman, a Radiology Professor at the University of California, San Francisco, whose study appears in the Archives of Internal Medicine, claimed that in order to get affected with the radiation an average person has to go through in excess of 50 airport scanners.

Moreover, the Transportation Security Administration (TSA) has assured the travelers and crew members about the safety of the backscatter X-ray machine installed for security purposes.

Responding to the uproar in people over the impact of radiation expose in airports, Smith-Bindman -- who has published several studies on cancer risks from overuse of medical imaging, claimed that a single CT scan is equivalent to 200,000 times of an airport scanner.
