Even before she was pregnant, Yolanda Marin-Czachor tried to avoid the full-body X-ray scanners that security officers use to screen airport passengers. Now she’s adamant about it: She’ll take a radiation-free pat-down instead any day.
“I had two miscarriages before this pregnancy,” Ms. Marin-Czachor, a 34-year-old mother and teacher from Green Bay, Wis., recalled, “and one of the first things my doctor said was: ‘Do not go through one of those machines. There have not been any long-term studies. I would prefer you stay away from it.’ ”
There are 244 full-body “backscatter” X-ray scanners in use at 36 airports in the United States. They operate almost nonstop, according to the Transportation Security Administration. Other airports use millimeter wave scanners, which look like glass telephone booths and do not use radiation, or metal detectors.
