Nuclear weapons today is one of the most powerful.Its development is carried out in many countries.Five of them are nuclear powers.It is the United States, China, Russia, France and Britain.Yet some States are engaged in research in this area, but have not yet reached the required level.The objectives pursued by them, not always humane.Therefore, its production should be reduced and kept under special control.
History long enough.But the first tests of nuclear weapons were held in 1945, when the United States dropped the bomb on the Japanese cities of Hiroshima and Nagasaki.There was a terrible accident.Destruction and casualties were numerous.Yet for many years the echoes of the explosions made themselves felt.
Nuclear Weapons by fission of heavy elements (plutonium, uranium, etc.).Its charge can be of several types.
Thermonuclear - is one of the species.Its effect is the synthesis of light metals.For this to happen, you need to create a very high temperature, which is achieved by an atomic explosion.
Neutron charge differs from previous large number of neutrons at the exit.
Finally, the net charge, which has a low amount of radioactive isotopes.
Nuclear Weapons consists of automation system and housing.This is its main elements.
housing acts as the container for nuclear charge and directly by the automation system.He also serves as protection against accidental damage and the external environment.The automation system is designed for the explosion only at certain times.It also prevents the accidental explosion of a charge.It consists of several parts: the undermining of charge, power supply, emergency undermine, undermine prevention and sensors.
to deliver weapons to the destination used by the winged, anti-aircraft and ballistic missiles and aviation facilities.
great power of nuclear weapons.It is divided into the following calibers: small, ultra-small, large, medium and extra-large.
nuclear weapons could be used in the air, under the ground or above the surface.An explosion is carried out in the air and can be high or low.Also distinguish land or underwater explosions that occur immediately above the surface, and underground or underwater.
How operates a nuclear weapon?Its explosion causes certain factors.Firstly, a mechanical impact.It produces a shock wave that occurs immediately after the explosion.Secondly, this thermal effect.This is a significant temperature rise in the affected area.After the explosion in Hiroshima, this area accounted for 4 kilometers.At this radius, the temperature reached a level at which the human body is transformed into ashes.Finally the impact that occurs as a result of a nuclear explosion, is radiation.It starts from the moment of the explosion, and continues for a very long time.
power of each of these stages depends on the type of charge.The farther away an object or a person on the localization of the explosion, the less the impact of nuclear weapons.
less powerful is the tactical nuclear weapons.It is designed to destroy individual targets.These include bombs, torpedoes, depth mines, etc.Such a weapon has virtually all the recognized nuclear powers.The total volume of this kind of charge does not exceed a few kilotons.
Humanity faces the task to prevent the proliferation of nuclear weapons and to prevent an arms race.It serves not only to peace, but also can cause the destruction of all humankind.
