Passengers who activated the metal detectors could choose which secondary security step they would prefer: a walk through the scanner or to be pat-down by a security officer. AirportsWhile the United States has operated full body scanners at airports across the country this year, the use of them was voluntary. Opposing opinions feel that public security is the highest priority, and that the technology available should be used to it's fullest in order to best protect innocent people's lives. Concern about children's rights and protection has also been an issue. The ControversyBecause the scanning machines provide such accurate images, some passengers and activist groups have opposed the use of them since they believe the images are an invasion of privacy. These scanners function similar to MRI machines, and are considered safe, as they expose passengers to only very minimal amounts of radiation. What are Full Body Scans?Much more detailed than typical X-rays, full body scanners are capable of viewing beneath layers of clothing, providing a map of the body's contours, any prosthetics under the skin, and both metallic and non-metallic objects. After the nearly missed bombing attempt during a Northwest/Delta flight flying from Amsterdam to Detroit on December 25th, airport security is turning to technology that may help identify non-metallic weapons and other concerns, such as the explosive device involved in the Christmas Day threat. Full body scanners may soon replace the metal detectors commonly used in airport security, both in the United States and abroad.
