=__**What are nuclear weapons?**__=
 * is an explosive device that derives its destructive force from nuclear reaction, either fission or a combination of fission or fusion aka atomic bomb.
 * both reactions release vast quantities of energy from relatively small amounts of matter.
 * the atomic bomb tested released the same amount of energy as approximately 20,000 tons of TNT.

=__**What are short and long term effects of nuclear weapon?**__=
 * these effects- including leukemia, cancer, tumors, and many others- appear two, three, even ten years later.
 * the decrease in white and red blood cells lasted for up to ten years after the bombing.
 * long after the acute effects of radiation have subsided, damage continues to produce a wide range of physical problems.
 * ** increase in cataract rate of the survivors. **
 * car tissue covering apparently healed burns began to swell and grow abnormally.


 * __What kinds of radiation are emitted in explosions brought about by nuclear weapons? __**
 * there are several kinds of radiation emitted; these types include gamma, neutron, and ionizing radiation, and are emitted not only at the time of detonation, but also for long periods of time afterward.
 * initial nuclear radiation is defined as the radiation that arrives during the first minute after an explosion, and is mostly gamma radiation and neutron radiation.
 * the level of initial nuclear radiation decreases rapidly with distance from the fireball to where less than one roentgen may be received five miles from ground zero.
 * initial radiation lasts only as long as nuclear fission occurs in the fireball. Initial nuclear radiation represents about 3 percent of the total energy in a nuclear explosion.
