A: Nuclear Weapons are an explosive device that derives it's destructive force from nuclear reactions, either fission or a combination of fission and fusion.


**Q: What are some of the short term and long term effects of their use?**

Long term - (Bone marrow death) Cataract induction, Cancer induction and Utero Effects.
=Nuclear Explosions (Radiation)=
 * ==Blast-- 40%-50% of total energy==
 * ==Thermal Radiation-- 30%-50% of total energy==
 * ==Lonizing Radiation-- 5% of total energy==
 * ==Residual Radiation-- 5-10% of total energy==

= = =Q: What kinds of radiation are emitted in explosions brought about by nuclear weapons?=



==A; 1). Nuclear Blast occurs when a nuclear bomb explodes. It causes destruction over a wide area within seconds to minutes. The blast creates a large fireball and a mushroom cloud of dust and particles. The fireball produces temperatures up to millions of degrees, shock waves similiar to a large earthquake,flashes similiar to lightning and intense radiation. The mushroom cloud carries radioactive materials from the bomb into the air. When the cloud settles down, dust and particles containing radioactive materials fall back to earth. This is called Fallout. Fallout can be carried by the wind and can contaminate the air, soil, food, and water.==

4). Fallout is the residual radiation hazard from a nuclear explosion, so called b/c it "falls out" of the atmosphere after the explosion.
