A ProPublica investigation looks into the new full-body x-ray scanners being deployed in airports around the country. In 1998 there were just 20 machines in the entire country. Today there are about 250 x-ray scanners in U.S. airports with plans for many more. Reporter, Michael Grabell writes that the technology hasn't been appropriately studied and poses significant radiation-related risks.
