Controversial ‘naked’ body scanners could be introduced at all UK airports after top scientists declared them safe.
Manchester Airport has been trialling the device – known as back scatter scanner – since 2009, but the European Commission halted new trials last year amid concerns there was a risk to passengers’ health from high levels of radiation.
But an EU study has decided that the risk from the scanners, which use X-rays to scan through clothing to produce images of passengers, is ‘close to zero’ and no greater than other factors.
A report said the radiation from a single passenger scan is ‘equivalent’ to the natural background radiation received within an hour on the ground or during ten minutes on a flight.
It added that the doses per scan were ‘well below the public dose limit’, although the long-terms effects, such as cancer risks, could not be dismissed entirely.
