What are Neutrons?
Neutrons are subatomic particles that can be expelled at high speed from a nuclues during fission and fusion. They can travel thousands of yards through air from a nuclear burst and have substantial penetrating power. They are not released by radioactive decay.
What are Gamma Rays?
Electromagnetic radiation similar to radio signals. They can travel thousands of yards through air and have great penertrating power. They can penetrate a ship's hull and superstructure and are not stopped by protective clothing. They are high waves of energy not particles. They are released in nuclear reactions and in radiactive decay.
What are Alpha particles?
A positive electrical charge that consist of two neutrons and two protons.
What are Beta particles?
A negative electrical charge that are released when a neutron decomposes released during nuclear reactions and radioactive decay. They can travel about 10 ft. in the air.
What is deep shelter?
