The backscatter systems work by generating small amounts of X-rays that reflect off the skin of an individual placed in the scanner. The scattered ionizing energy of the X-rays is then picked up by sensitive detectors and processed by a computer to produce a two-sided image. The resulting image is a revealing chalk-like outline that has been the cause of debate since its implementation. The backscatter scanners operate at 50 kVp producing X-rays with a tenth value layer (TVL) of about 8 cm in tissue (Moulder, 2012). Transportation Security Officers (in federal airports) or private contract screeners (in nonfederal airports) operate these units and it takes approximately 15 s to complete a scan. Traditional backscatter scanners require one operator to direct the passenger through the scanner while another operator is stationed in a private location to analyze the image that comes through to the computer. Rapiscan Secure 1000™, manufactured by Rapiscan Systems has an internal monitoring system that prevent over exposure of X-rays to passengers. These systems consist of sensors and detectors that enable the scanner to default to a power-down state if it is not operating within the set critical parameters (http://www.rapiscansystems.com).
