  3. Nuclear bombs have had yields between 10 tons TNT (the W54) and 50 megatons for the Tsar Bomba (see TNT equivalent). A thermonuclear weapon weighing little more than 2,400 pounds (1,100 kg) can release energy equal to more than 1.2 million tons of TNT (5.0 PJ)
  4. The Tsar Bomba, as the test was ultimately known, had a yield between 50 and 58 megatons, twice the size of the second-largest nuclear blast. 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. The first atomic bomb.

The size of the nuclear fireball is a function of yield, t he height of burst, and the surrounding environment. The nuclear fireball is tens of millions of degrees (i.e., as hot as the interior of the sun). Inside the fireball, the temperature and pressure cause a complete desintegration of molecules and atoms 3D Comparison | This video shows the comparison of nuclear weapons in 3DThese are the real size and human model is about 6 feet tall.On my channel, you will.

Nuclear weapons, such as the bomb dropped on Hiroshima, which was 15 kilotons of chemical explosives, produced lethal ionizing radiation in addition to a shock wave and massive amounts of heat. Nuclear weapons also have radioactive fallout, where debris is picked up by winds into the atmosphere and then settles back to Earth days later Thermonuclear bomb, weapon whose explosive power results from an uncontrolled self-sustaining chain reaction in which isotopes of hydrogen combine under high temperatures to form helium in a process known as nuclear fusion. The temperatures required for the reaction are produced by the detonation of an atomic bomb Well, the largest nuclear bomb ever detonated, the Soviet Union's Tsar Bomba, had a yield of just 50 megatons.

The National Resources Defense Council estimated the total yield of all nuclear tests conducted between 1945 and 1980 at 510 megatons (Mt). Atmospheric tests alone accounted for 428 mt, equivalent to over 29,000 Hiroshima size bombs. The amount of radioactivity generated by a nuclear explosion can vary considerably depending upon a number of. The total explosive yield of nuclear weapons tested on the Marshall Islands was the equivalent of dropping 1.6 Hiroshima-sized bombs every day over the 12 years of U.S. nuclear testing. During the 1954 Castle Bravo test of a warhead 1,000 times more powerful than the bomb dropped on Hiroshima, no warning or evacuation orders were given to local inhabitants While low-yield nuclear bombs can range from .1 kilotons to 10, 20, or 50 kilotons, according to Cirincione, the explosive yield from a low-yield nuclear weapon is equivalent to 1,000 MOABs. That is equivalent to the sizes of bombs dropped by the U.S. over Nagasaki and Hiroshima at the end of World War II The first atomic bombs were detonated during World War II. First, a test bomb exploded in the New Mexican desert. Then, bombs were dropped on two unsuspecting Japanese cities The North Korea nuclear test in early September 2017 was so powerful that it resulted in an entire mountain being lifted off the ground and was the equivalent of 17 times the size of the bomb.
