What type of detector is used for explosive ordnance?

• A. Smoke detector
• B. Temperature detector
• C. Metal detector
• D. Radiation detector

Answer: (C)

The use of a metal detector for explosive ordnance is grounded in its ability to identify metallic components commonly found in bombs and other explosive devices. Metal detectors operate by generating an electromagnetic field and detecting disturbances caused by metallic objects within their range. This capability is crucial in the military and security contexts, where identifying hidden explosives for safe disposal or neutralization is paramount.

While smoke detectors are designed to sense smoke from fires and temperature detectors monitor changes in heat, neither is suited for detecting explosive materials. Similarly, radiation detectors are effective for identifying radioactive materials but do not detect explosives that do not emit such radiation. Therefore, a metal detector is the most appropriate and effective choice for locating explosive ordnance due to its specific design and function in identifying metal content.
