Unit 4 Nuclear Threat 4-3 In this section, you will learn about the different types of hazards that result from a nuclear detonation. The energy yielded immediately by a blast presents hazards from blast or shock effects, thermal radiation effects, and nuclear radiation effects . You will also learn how longer-term hazards, such as radioactive fallout, could result from a nuclear detonation. Types of Burst The destructive forces associated with a nuclear explosion vary with the location of the point of burst in relation to the surface of the earth. The main types are: O High Altitude Burst. Detonation above 100,000 feet. Destructive forces do not significantly affect the ground. O Air Burst. The fireball does not touch the ground. Detonation is below 100,000 feet. O Surface Burst. Detonation occurs at or slightly above the actual surface of the earth. The blast kicks up considerable radioactive debris. “Dirty Bomb” O Sub-surface Burst. Detonation occurs under ground or under water. Depth determines destructive
