Mandating digital is carbon dating the same as radiometric dating
In the case of airline passenger screening it is her nude form.The image resolution of the technology is high, so details of the human form of airline passengers present privacy challenges.Airport security has undergone significant changes since the terrorist attacks of Sept. Recently, the Transportation Security Administration (TSA) announced a proposal to purchase and deploy "Whole Body Imaging" X-ray machines to search air travelers at all airports.TSA said it believes that use of the machines is less invasive than pat-down searches.Since June 13, 2009, full-power television stations nationwide have been required to broadcast exclusively in a digital format.The switch from analog to digital broadcast television is known as the Digital Television Transition.EPIC has filed a lawsuit to suspend the deployment of body scanners at US airports, pending an independent review.Body scanners produce detailed, three-dimensional images of individuals.
DTV enables broadcasters to offer television with better picture and sound quality, and multiple channels of programming.The Department of Homeland Security is requesting million to invest in detection systems, which includes funding for the backscatter machines, which cost between 0,000 and 0,000 each.The backscatter machines use high-energy X-rays that are more likely to scatter than penetrate materials as compared to lower-energy X-rays used in medical applications.The image resolution of the technology is high, so the picture of the body presented to screeners is detailed enough to show genitalia.These images are not necessarily temporary - screeners can save the body images to the system's hard disk or floppy disk for subsequent viewing on either "the system monitor or on any IBM compatible personal computer with color graphics." The Transportation Security Administration claims that is not storing detailed images of passengers screened by the system.

One such technique called "backscatter" X-Ray is based on "the emergence of radiation from that surface of a material through which it entered.
