A hydrogen bomb has never been used in battle by any country, but experts say it has the power to wipe out entire cities and kill significantly more people than the already powerful atomic bomb, which the U.S. dropped in Japan during World War II, killing tens of thousands of people.
Hydrogen bombs of more than 50 megatons have been detonated, but the explosive power of the weapons mounted on strategic missiles usually ranges from 100 kilotons to 1.5 megatons.
The Ivy Mike shot of 1 November 1952, at Enewetak Atoll, was the first full test of a Teller-Ulam design "staged" hydrogen bomb, with a yield of 10 megatons.
Depending on its impact radius, even a Tsar bomb cannot destroy a whole country. Only a small country such as Vatican City or Monaco with land areas of 44 ha and 202 ha respectively can be completely destroyed using a nuclear weapon.
But a hydrogen bomb has the potential to be 1,000 times more powerful than an atomic bomb, according to several nuclear experts. The U.S. witnessed the magnitude of a hydrogen bomb when it tested one within the country in 1954, the New York Times reported.
The Tsar Bomba packed a punch of over 50 megatons, which is the equivalent of 50 million tons of conventional explosives. That's 10 times more powerful than all the munitions expended during World War Two and over 1,500 times the force of the atomic bombs dropped on Hiroshima and Nagasaki combined.
Neutron bombs, or more precisely, enhanced [neutron] radiation weapons were also to find use as strategic anti-ballistic missile weapons, and in this role, they are believed to remain in active service within Russia's Gazelle missile.
The radiation in Hiroshima and Nagasaki today is on a par with the extremely low levels of background radiation (natural radioactivity) present anywhere on Earth. It has no effect on human bodies.
Tsar Bomba (in Russian, Царь-бомба) is the Western nickname for the Soviet RDS-220 (РДС-220) hydrogen bomb (code name Vanya). Detonated by the Soviet Union on October 30, 1961, Tsar Bomba is the largest nuclear device ever detonated and the most powerful man-made explosion in history.
A declassified document shared by nuclear historian Alex Wellerstein gives the verdict that scientists at the Los Alamos laboratory and test site reached in 1945. They found that "it would require only in the neighborhood of 10 to 100 Supers of this type" to put the human race in peril.
Russia's Tsar bomba: World's most powerful nuclear weapon of mass destruction.
Tsar Bomba, (Russian: “King of Bombs”) , byname of RDS-220, also called Big Ivan, Soviet thermonuclear bomb that was detonated in a test over Novaya Zemlya island in the Arctic Ocean on October 30, 1961. The largest nuclear weapon ever set off, it produced the most powerful human-made explosion ever recorded.
Called "Tsar Bomba," it exploded with the force of 50 to 60 megatons of TNT, making it the largest nuclear explosion ever unleashed, George William Herbert, an adjunct professor at the James Martin Center for Nonproliferation Studies in California, told Live Science.
As only one bomb was built to completion, that capability has never been demonstrated. The remaining bomb casings are located at the Russian Atomic Weapon Museum in Sarov and the Museum of Nuclear Weapons, All-Russian Scientific Research Institute Of Technical Physics, in Snezhinsk.
But assuming every warhead had a megatonne rating, the energy released by their simultaneous detonation wouldn't destroy the Earth. It would, however, make a crater around 10km across and 2km deep. The huge volume of debris injected into the atmosphere would have far more widespread effects.
A new video simulates the explosion of thermal nuclear weapons in the Challenger Deep. Tsar Bomba is the most powerful nuclear bomb ever made. One bomb would be stanched, but a million could easily destroy the Earth.
Most uranium found naturally in the world exists as uranium-238, leaving only 0.7% of naturally existing uranium as the U-235 isotope. When a neutron bombards U-238, the isotope often captures the neutron to become U-239, failing to fission, and thus failing to instigate a chain reaction that would detonate a bomb.
Thermonuclear bombs can be hundreds or even thousands of times more powerful than atomic bombs.
Antimatter-matter annihilations have the potential to release a huge amount of energy. A gram of antimatter could produce an explosion the size of a nuclear bomb.
But a hydrogen bomb has the potential to be 1,000 times more powerful than an atomic bomb, according to several nuclear experts.
Edward Teller is often referred to as the “father of the hydrogen bomb.” After the Soviet Union detonated its first atomic bomb in 1949, Teller worked to convince President Truman to develop a crash program for the hydrogen bomb, which he believed was feasible.
This gun-type uranium bomb, nicknamed Little Boy, weighed 9,700 pounds. The bomb was dropped on Hiroshima, Japan, August 6, 1945, at 8:15 AM. A B-29 dropped the bomb from 31,000 feet. The bomb exploded about 1,500 feet above the city with a force of 15,000 tons of TNT.
