What type of weapon is a "dirty bomb"?

• A. Chemical
• B. Radiological
• C. Explosive
• D. Biological

Answer: (B)

A dirty bomb is a radiological dispersal device. Its defining feature is to spread radioactive material using a conventional explosive, contaminating the area and creating fear and disruption rather than relying on the explosive blast alone. The purpose is radiological contamination, not to cause chemical harm or biological infection, nor is it simply an ordinary explosive device without radioactivity. So the correct category is radiological because the key characteristic is dispersal of radioactive material.
