This is recycled content from last October. Past discussion: http://news.ycombinator.com/item?id=4674309 http://news.ycombinator.com/item?id=4674309 I will mention that IAD airport in TSA's backyard still have a complete array of Rapiscan scanners, with no sign of being replaced. Each scanner is slightly rotated away from the next. One might postulate that the xray leakage off to the sides of the scanners would have a compounding effect on TSA workers if the scanners were arranged perfectly in line.
