Is Airport Security Effective? | The Scientific Breakdown

What type of material is often colored orange in an airport bag scanner image because it contains carbon?

• Metals

• Organic materials

• Plastics

How do metal detectors at airports identify metal objects?

• They use sound waves to bounce off metal.

• They create a magnetic field that interacts with metal, causing an alarm.

• They shine a light that reflects off shiny metal surfaces.

• They measure the weight of objects passing through.

• Backscatter X-ray scanner

• Metal detector

• Millimeter wave scanner

• Explosives Trace Detection machine

What is the name of the process used by Explosives Trace Detection (ETD) machines to identify suspicious compounds?

• X-ray imaging

• Ion mobility spectrometry

• Magnetic field detection

• Microwave reflection
