Nuclear Weapons
Nuclear Weapons
-INTRODUCTION
Nuclear weapons are explosive devices
designed to release nuclear energy on a large
scale.
Nuclear explosives involve energy sources within
the core, or nucleus, of the atom.
FISSION WEAPONS
* Albert Einstein, E=mc2 .
* Split of uranium.
THE CHAIN REACTION
* Series of nuclear fissions.
CRITICAL MASS
* Mass of U needed for the
explosion.
- DETONATION OF ATOMIC BOMBS
* Gun-type weapon.
* Implosion weapon.
-PRODUCTION OF FISSILE MATERIAL
A- Separation of Uranium Isotopes
B- Producing Plutonium
-THERMONUCLEAR, OR FUSION,
WEAPONS
* Fusion reaction.
* Development of H-bombs.
-THERMONUCLEAR TEST
* The Mike test .
* The Lucky Dragon.
FISSION-FUSION-FISSION BOMB
* No chain reaction.
EFFECTS OF NUCLEAR WEAPONS
A- Blast Effects
* Expansion wave.
B- Thermal Effects
* The fireball.
C- Penetrating Radiation
* The prompt radiation.
* The fallout.
D- Climatic Effects
* The nuclear winter.
E- Clean H-Bombs
*The neutron bomb.
