The four nuclear explosion categories are defined by which parameter?

• A. Height of Burst (HOB)
• B. Yield
• C. Distance
• D. Time of Day

Answer: (A)

Where the detonation occurs relative to the ground sets the category of a nuclear explosion: subsurface, surface, airburst, or high-altitude. This grouping is defined by the Height of Burst, the parameter that determines how the energy interacts with the atmosphere and surface. Yield—the total energy released—doesn't define the category by itself, and distance or time of day don’t determine the explosion environment either. The height of burst governs the distinctive blast patterns, thermal effects, and fallout behavior you must anticipate in damage control planning.
