detection of explosives

Detecting explosives involves specialized tools that identify traces of explosive materials or their unique chemical signatures. Techniques include using sensors like ion mobility spectrometers, which analyze particles or vapors in the air, or dogs trained to sniff out specific scents. Sometimes, devices use X-rays or gamma rays to see inside packages for suspicious objects. These methods are highly sensitive and can quickly screen luggage, cargo, or areas for potential threats, helping ensure safety in public spaces and security checkpoints while minimizing disruptions.
