experiments of nuclear weapons of mass destruction

After World War II era that is characterized by the atomic bombs dropped on Hiroshima and Nagasaki, two large blocks of time (the United States and the Soviet Union) continues to conduct experiments of nuclear weapons of mass destruction. Tensions in the Cold War era to the era of 80s and ended with the collapse of the Soviet Union (USSR) when it made two big blocks are constantly trying to create a lethal weapon that not only has the potential as a weapon of mass destruction but also destruction of human civilization.
Quote:Here's three largest nuclear bomb after the World War II era ever detonated human:3. Bomb Ivy Mike

Ivy Mike was the code given in the test the first nuclear fusion bomb the United States. Tnaggal detonated on 1 November 1952 on a coral island in the Pacific Ocean as part of Operation Ivy test. The bomb was the first full test of the Teller-Ulam design, a single stage fusion bomb, and is considered the first hydrogen bomb test is successfully exploded.

Bomb "Mike" weighing 62 tonnes, designed by Richard Garwin, a student of Enrico Fermi, is actually physically more like building a factory rather than a weapon. At the center there is a giant cylindrical bottle thermo flask or cryostat, which stores the deuterium-tritium fusion materials. Common fission bomb (primary section) at the end used to create the conditions that trigger the fusion reaction.Its primary stage was a TX-5 fission bomb in a separate room at the top of a series of real bombs. Secondary fission stage using liquid deuterium-tritium. Underneath is a a cylindrical rod of plutonium (for ignition / sparkplug), which is used to trigger the fusion Raksi. Surrounding this series is a natural uranium tamper weighing 4.5 tons.; Interior forming a tunnel for guiding radiation X-rays from the primary to the secondary. X-rays point here is to to compress the secondary part hydrodynamically, increasing density and temperature to a level that conditioned deuterium thermonuclear reactions, and to compress the sparkplug to ignite supercriticality conditions. The outer part is made of a steel casing 25-30 cm thick. The whole series is dubbed "Sausage" is 2.03 meters in diameter and 6.2 meters high and weighing up to 54 tons. While the whole "building" this monster bomb weighed 82 tonnes of aluminum in the form of the building called "shot cab", located on the island Elugelab, Pacific, part of the Enewetak atoll.
Explosion test conducted on 1 November 1952 at 07:15 AM and produces the explosion of a bomb estimated at magnitude 10.4 to 12 megatons. However 77% final trigger came from fast fission process of uranium tamper., Which means the bombings produces radioactive waste that was great too.
The fire ball as wide as 5.2 km, and cloud cendawannya reach a height of 17 km in less than 90 seconds. A minute later reaching 33 km before it stabilized at a distance of 37 km in diameter at its peak stretched to a diameter of 161 km. The explosion created a crater 1.9 km in diameter and within 50 meters and resulted in a 20-foot waves in the ocean, also left the area around the atoll heavily contaminated for some time.
2. Bomb Castle Bravo

Castle Bravo was the code name given to the first thermonuclear hydrogen bomb made in the United States was a magnitude 15 megatons. The bomb was detonated on March 1, 1954 in Make Atollm Marshal Islands as part of Operation Castle tests. Radioactive garbage into secret radiation tests negative effects that contaminate the population in the vicinity of the test including the crew of the Japanese vessel Daigo Fukuryū Maru ("Lucky Dragon No.. 5") and harsh international criticism due to the risk of atmospheric termonuklirnya. Explosive power of the bomb was equivalent to 1200 times the explosive power of the bomb dropped on Hiroshima atm and Nagasaki in 1945 during World War II.
This bomb uses deuteride fusion for his stage and not using cryogenic liquid as before the project which produces bomb Ivy Mike with a small office building of physical and not very practical to use in the war. By using this new material Castle Bravo was the first fusion bomb made in the United States are practical and deliverable.
This bomb uses aluminum for its chassis, unlike the steel used Ivy-Mike. Embedded in the cylinder casing smaller cylinders containing lithium deuteride fusion materials (secondary) with a fission atomic bomb at the end of a section. Work in the secondary section is an a cylindrical rod of plutonium (for ignition / sparkplug), which is used to trigger the fusion Raksi. Surrounding this series is a natural uranium tamper.; Space between the tamper and casing forming a tunnel for guiding radiation X-rays from the primary to the secondary. X-rays point here is for the secondary section to compress, increasing density and temperature to a level that conditioned deuterium thermonuclear reactions, and to compress the sparkplug to ignite supercriticality conditions.
This bomb has a weight of 10.7 tons with a length of 4.6 meters and 1.4 meters wide and is placed in position on an artificial island on the reef off the coast of Namu Island, Bikini Atoll.
When detonated, the fireball created in a second area of ​​7 km in diameter. The fireball seen in the Kwajalein atoll, 450 km from ground zero. The explosion left a crater 2km wide and within 75 meters. The mushroom cloud reached a height of 14 km and a diameter of up to 11km preformance minute. In less than 10 minutes extends to a height of 40km and 100km diameter (extends 6km permenitnya). As a result, the cloud area of ​​7000 miles in the Pacific Ocean contaminated including small islands such as Rongerik, Rongelap and Utirik.
