Which one of the following is the full form of X-BIS ?

X-BIS stands for X-ray Baggage Inspection System. It is a standard security screening technology deployed at airports, railway stations, and high-security buildings to inspect the contents of luggage without opening them. The system works by passing X-ray beams through baggage; sensors on the opposite side detect the radiation that penetrates, creating a detailed image on a monitor.

• These systems utilize dual-energy technology to differentiate materials based on their effective atomic number (Z_eff).
• In a typical X-BIS display, orange represents organic materials (including explosives and narcotics), blue represents metals, and green represents inorganic or mixed materials.
• In India, these systems are regulated by the Bureau of Civil Aviation Security (BCAS) and must meet safety guidelines issued by the Atomic Energy Regulatory Board (AERB) regarding radiation leakage.
