B.O.S.S. is an acronym for Body Orifice Security Scanner. The B.O.S.S. chair was developed to assist law enforcement with performing a non-invasive and non-intrusive body cavity search for metal contraband. Since the B.O.S.S. unit is a metal detector and NOT an x-ray scanner, it poses no radiation health risk to pregnant women or pacemaker patients. Today there are B.O.S.S. chairs in use worldwide.
