Nuclear Emergency

Nuclear Explosion- An explosion with intense light and heat, a damaging pressure wave and widespread dispersion of radioactive material that can contaminate the air, water, and ground surfaces for miles around. A nuclear device can range from a large weapon carried by a missile to a small portable nuclear device transported by an individual.

Nuclear Fallout - Minute particles of radioactive debris that descend slowly from the atmosphere after a nuclear explosion.

Radiation - Radiation is energy that comes from a source and travels at the speed of light. This energy has an electric field and a magnetic field associated with it, and has wave-like properties.
