Enriched Uranium/Plutonium starts reaction
Shot together or compressed
Leave behind radioactive remains Fusion Weapons
Use deuterium and tritium (hydrogen)
Fission bomb compresses hydrogen
Less radiation left behind Light Blue: Non-Proliferation Treaty nuclear weapons holders
Dark Blue: NATO nuclear weapon sharing states
Red: other states with nuclear weapons
Green: states formerly holding nuclear weapons Dirty Bombs
Use non-nuclear explosion
Radioactive material scattered by the explosion
Radiation probably not enough to cause death
High costs for area
Could be used for terrorism Nuclear Weapon Delivery
"Atomic Annie" Aftermath of a Nuclear War
Radiation can cause mutations
First explosions would cause nuclear darkness
Blocked sunlight would cause nuclear winter
Burning releases carbon dioxide
Nuclear summer would follow Cuban Missile Crisis
Spy plane discovered missile site
JFK had Cuba blockaded
Missiles removed, US would not invade
