Explosive Trace Detection (ETD)
Explosive Trace Detection (ETD) is a security technology used to identify tiny traces of explosive materials on people, objects, or luggage. It works by collecting samples from surfaces or belongings and analyzing them with specialized sensors that detect chemical signatures specific to explosives. ETD devices are commonly used at airports and security checkpoints to prevent threats without causing inconvenience. They are sensitive enough to find minute residues, ensuring safety while allowing quick and non-invasive screening of travelers and cargo.
