The European Commission decided in November to ban airport body scanning X-ray backscatter machines after studies found a small number of cancer cases linked to use of the devices. The decision affects all airports in Europe, with an exception for U.K. airports that will be allowed to test them, but not deploy them permanently. According to the European Commission, "only security scanners which do not use X-ray technology are added to the list of authorized methods for passenger screening at EU airports." The commission does approve of full non-X-ray body scanners (radio wave scanners are among those used in the U.S.) when operated under specific guidelines and restrictions. In the U.S., the TSA uses more than 250 backscatter machines at the nation's 100 busiest airports and is unmoved by Europe's position. The degree of cancer risk varies somewhat depending on the source ... as does the degree of usefulness of the machines themselves.
