Explosive detection is the field of research dedicated to developing technologies and methods for detecting and identifying explosives in various environments. This area of research is crucial for enhancing security measures in locations such as airports, train stations, and military facilities to prevent potential terrorist attacks or accidents. Technologies used in explosive detection range from traditional methods such as trained canine teams to advanced technologies such as trace detection systems, X-ray scanners, and spectroscopy techniques. Researchers in this field constantly work to improve the sensitivity, reliability, and speed of explosive detection methods to stay ahead of evolving threats and ensure the safety of the public.
