when a passenger puts their bags through an X- ray machine they go through a type of electromanetic energy Unlike visible light humans cannot see X- ray In hospitals these X-ray energy beams can see through skin tissue to detect broken bones tumors or other injuries In an airport X-ray technology is used in CT computer tomography scanners Suitcases from passengers ride along a conveyor belt and pass through the hollow CT scanning machine the X-ray bounce off the object inside the suitcases measuring the density and mass of each object All that data is immediately entered into a computer CT scanners are more complex than metal detectors and can analyze chemical components in addition to metallic object If the density and mass of items in the suitcase match items that are known to be dangerous the object are removed from the suitcase
