A computer screen shows a scan of a security official in a RapiScan full-body scanner being trialled at Manchester Airport in Manchester, northern England January 7, 2010. The radiation risk from full-body scanners used to improve airport security is low and unlikely to raise an individual’s risk of cancer, U.S. experts said on yesterday. Airports in Britain, the Netherlands and Canada have said they plan to use full-body scanners to foil future terror attempts like the Christmas Day attempt to blow up a Detroit-bound flight. The United States has tested 40 whole-body scanners as part of a pilot program started after the Sept. 11 attacks, and this past October ordered 150 more.
