There have been several threads here, often started by exbayern quoting German news sources. There were false positives caused by pleats, zippers, sweat stains and posture. According to one report, most passengers either needed a second scan or a patdown, or both.

The technology tested and rejected by Germany was the millimetre wave (MMW = radio) technology, exactly as used in many US airports. The US also uses backscatter (= x-ray = ionizing radiation) scanners.
