The European Commission adopted new rules Nov. 14 regarding X-ray, or backscatter, body scanners at all airports in Europe. A press release ordered members of the European Union to remove X-ray scanners from its airports to avoid risking citizens' health and safety." The news [brings] into question the continued use of the very same X-ray scanners in U.S. airports. While the Transportation Security Administration also employs millimeter-wave scanners in U.S. airports, X-ray scanners are the ones that have received more criticism from public-safety advocates. While ... the amount of radiation exposure from X-ray machines is very low, several studies have shown that a small number of cancer cases could result from scanning millions of passengers every year. Some critics of the scanners say that any small amount of cancer is too much to tolerate. Although the TSA doesn't show signs of budging on the use of X-ray scanners, Europe will instead use machines that rely on radio frequency waves, which have not been linked to cancer.

Each news summary is created according to strict standards. Here's how we do it.
Each summary is created using a consistent editorial procedure. The target length is approximately 16 lines of 11-point Arial text in a 650-pixel-wide column. Up to 25% of a summary may be set in bold to emphasize the most important ideas. Summaries are composed of verbatim excerpts presented in the same sequence as they appear in the original news source, with very minor editorial additions. Where material has been omitted between excerpts, the omission is indicated with ellipses (...). Any words added by an editor for clarity or context appear in [brackets]. Our original news editor was Fred Burks. Tod Fletcher edited most summaries from 2007 through 2014, and Mark Bailey has served as news editor since 2014.
