Critics have said the TSA's X-ray machines are an invasion of privacy, and some have suggested the radiation they emit could cause cancer. TSA has defended the machines as being safe, and the agency recently announced that its newest machines would use generic outlines of human bodies to identify potential threats, instead of specific images of passengers being screened.
The agency has also touted a move toward a "risk-based" security system, pointing to measures like its Pre-Check known traveler program, where passengers submit background information about themselves in exchange for the possibility of expedited screening.
