Which category of attacks would use devices to disperse radioactive materials?

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

Answer: (D)

The category that specifically involves the use of devices to disperse radioactive materials is radiological. This type of attack utilizes substances that emit radiation, which can affect human health and the environment by contaminating air, water, and soil. Radiological dispersal devices, commonly known as "dirty bombs," are designed to scatter radioactive materials, leading to increased exposure and fear, even if the immediate blast is not as destructive as other explosive devices. This category distinctly focuses on the nature of the material (radioactive) and the method of dispersal, setting it apart from chemical or nuclear attacks, which involve different types of hazardous substances or actions.
