A thermonuclear weapon weighing little more than 2,400 pounds (1,100 kg) can produce an explosive force comparable to the detonation of more than 1.2 million tons of TNT (5.0 PJ) A nuclear device no larger than traditional bombs can devastate an entire city by blast, fire, and radiation. It is shaped like a sphere. The explosive force of the device — nicknamed Tsar Bomba, or the Tsar’s bomb, and set off on Oct. 30, 1961 — was 50 megatons, or the equivalent of 50 million tons of conventional explosive. At least three of those countries -- the U.S., Russia and China -- could strike any target anywhere in the world. The top of the sphere contains conventional chemical explosives surrounding a sphere of beryllium mirror casing, inside of which is a smaller uranium or plutonium sphere about 4 to 6 inches in diameter.

Fat man … A bomb of this size would create a fireball 6.4 square miles large and would be able to give humans third-degree burns within 4,080 square miles of the bomb's epicentre. naval gun, a subcritical projectile of U-235 was fired at a subcritical target of U-235. The bomb was 8m long (26ft), had a diameter of nearly 2.6m (7ft) and weighed more than 27 tonnes. Meanwhile, Edward Teller was hell-bent on building hydrogen bombs capable of unleashing hundreds of times more energy than the bombs dropped on Hiroshima and Nagasaki. Between 90,000 and 166,000 people are believed to have died from the bomb in the four-month period following the explosion. Sort by: Top Voted. The United Nations.

The bomb was dropped on Washington, D.C. during the Great War in 2077; however, it remained undetonated in its crater. Below this atomic bomb is the hydrogen or fusion bomb. When a free neutron hits the nucleus of a fissile atom like uranium-235 ( 235 U), the uranium splits into two smaller … Nicknamed “Little Boy” (for President Franklin Roosevelt), the bomb’s size was 3 meters in length by 0.7 meter in diameter, using uranium 235 as its critical material. size of a softball; Plutonium core surrounded by 5,300 lbs of high explosives; plutonium core reduced to size of tennis ball; Bomb Initiator: Beryllium - Polonium; All components of Fat Man ferried to Tinian Island aboard B-29's of the 509th Composite Group; Efficiency of weapon: 10 times that of Little Boy But a hydrogen bomb has the potential to be 1,000 times more powerful than an atomic bomb, according to several nuclear experts. The nuclear explosion compresses … This is the currently selected item. The RDS-220 hydrogen bomb, also known as the "Tsar Bomba", is the biggest and most powerful thermo nuclear bomb ever detonated. NukeMap. The effects of a nuclear bomb depend a lot on the height of the detonation. But in a multi-stage atomic bomb, a small fission bomb is placed around material that's suitable for nuclear fusion. As Japan marks 75th anniversary of the nuclear bomb attack, a look at how it happened, the devastation it wrought. At the time of the bombing, Hiroshima was home to 280,000-290,000 civilians as well as 43,000 soldiers. Practice: The Second World War.

Dubbed the Mark I (Model 1850) and code-named "Little Boy," the bomb's uranium was not available until July. Its weight was 9700 pounds. In a nutshell, an atomic bomb is a fission device, while a hydrogen bomb uses fission to power a fusion reaction.
