Which equipment is used to detect contraband in articles such as shoes and clothes?

• A. X-ray scanners
• B. Notepad
• C. Bags
• D. Canines

Answer: (A)

Identifying contraband inside garments and footwear relies on imaging equipment that can see through the item without opening it. X-ray scanners fit this purpose because they send radiation through the object and capture an image of its internal contents. Different materials attenuate X-rays in different ways, so hidden items—whether metal, dense substances, or unusual shapes tucked into seams, soles, or pockets—often appear as distinct, recognizable features on the screen. This allows inspectors to spot contraband inside shoes or clothing quickly and non-destructively. Notepad, bags, and canines aren’t the detection equipment in this context. A notepad is just for writing, and bags are containers that items might be placed in rather than a tool for detecting them. Canines can detect odor and are used in screening, but they are living detectors rather than equipment.
