In a dirty bomb scenario, what is the primary hazard?

• A. Radiation contamination
• B. Chemical exposure
• C. Biological release
• D. Secondary blast

Answer: (A)

In a dirty bomb, the main danger is radiological contamination. The device combines an ordinary explosive with radioactive material, so when it detonates, radioactive particles are spread into the surrounding area. The real health risk comes from these contaminants sticking to skin, clothing, and surfaces, or being inhaled or ingested, which can cause external and internal exposure and long-lasting hazards. This drives the response toward decontamination, contamination control, and monitoring to prevent further exposure, rather than focusing on just the blast energy. Chemical exposure and biological release describe hazards from different kinds of threats and aren’t the defining feature of a dirty bomb. The blast effect can cause injuries, but the dominant concern in a dirty bomb scenario is the spread and cleanup of radioactive contamination.
