But the survey also revealed that 80 percent of respondents were not aware that there are full-body scanners that do not expose people to radiation and a similar percentage said that if they knew a non-radiating full-body scanner was available in airports they would be more willing to agree to be scanned. The survey commissioned by Millivision, a developer of non-radiating scanners using passive millimeter technology sheds new light on the public's willingness to accept alternatives to traditional scanners which have been the focus of concern and controversy. Millivision full-body scanning systems detect threats with none of the health concerns associated with these other systems. Millivision systems also employ privacy controls that address concerns raised by the public over the images generated by traditional scanners. The survey found that 70 percent of respondents would be more willing to submit to scans if privacy-protection features were being used. "This survey provides new insights into the controversy around the current generation of full-body scanning systems, showing us that the public would be far more open to scanners that addressed their concerns around radiation exposure and privacy," said Paul Nicholas, CEO of Millivision. "While it's clear that consumers understand the important role these systems can play adding another level of security these survey findings are a signal to the security community that non-radiating scanners would remove an obstacle to their adoption, alleviating the public's growing safety and privacy concerns." Regarding radiation exposure, 60 percent of respondents are aware that they are being exposed to X-ray radiation when they go through a Backscatter full-body scanner, while fewer than 35 percent were aware that they were being exposed to electromagnetic (microwave) radiation when going through an active millimeter wave full-body scanner. The two technologies currently deployed for airport security. After knowing about exposure to radiation with Backscatter X-ray and active millimeter wave full-body scanners, 60 percent of consumers said they would be less likely to agree to a full-body scan and instead receive a pat-down. Unlike Backscatter and active millimeter wave systems, Millivision full-body scanning systems do not expose travelers to radiation associated with Backscatter and active millimeter wave systems but can still detect objects that would not be identified by metal detectors.
