By 2014, the Transportation Security Administration plans to deploy body scanners at almost every airport security lane in America. The TSA uses two types of scanners: the millimeter wave and the X-ray backscatter. In our ongoing investigation, we’ve exposed details about each scanner’s health risks, false alarm rates and effectiveness. But to break it down further, here’s a side-by-side comparison of both types. Passengers can decline either scanner and get a pat-down instead.
