"Susan Hallowell, the director of the U.S. Transportation Security Administration's security laboratory, allows her body to be X-rayed by the 'backscatter' machine that bounces X-rays off the skin, producing a black-and-white image. To the eye, she is dressed in a skirt and blazer in dark, businesslike colors. On the monitor she is a NAKED, BRAIN-EATING ZOMBIE, except for a gun and a bomb that she hid under her outfit.

"It does basically make you look fat and naked, but you see all this stuff," Ms. Hallowell said.
The agency hopes to modify the machines with an electronic fig leaf - programming that fuzzes out sensitive body parts or distorts the body so it does not appear so, well, graphic.
Some were uncomfortable with the technology - called "backscatter" because it scatters X-rays - while others proclaimed it "a whole lot nicer than having someone pat me down," he said. [...] With backscatter technology, rays deflected off dense materials such as metal or plastic produce a darker image than those deflected off skin. The radiation dosage is about the same as sunshine, Ms. Hallowell said.
