The result, according to the Union of Concerned Scientists (opens in new tab), is a fireball with temperatures that match the heat of the center of the sun. Thermonuclear bombs have been tested, but never used in combat. Needless to say, being at ground zero of such an explosion means instant death.

What happens when a thermonuclear bomb explodes?
The result, according to the Union of Concerned Scientists (opens in new tab), is a fireball with temperatures that match the heat of the center of the sun. Thermonuclear bombs have been tested, but never used in combat. Needless to say, being at ground zero of such an explosion means instant death.

Do thermonuclear bombs give off radiation?
This would complete the fission-fusion-fission sequence. Fusion, unlike fission, is relatively “clean”—it releases energy but no harmful radioactive products or large amounts of nuclear fallout.
Can a thermonuclear bomb destroy a city?
A thermonuclear weapon weighing as little as 600 pounds (270 kg) can release energy equal to more than 1.2 megatonnes of TNT (5.0 PJ). A nuclear device no larger than a conventional bomb can devastate an entire city by blast, fire, and radiation.
How destructive is hydrogen bomb?
Hall, director of the University of Tennessee’s Institute for Nuclear Security, called the hydrogen bomb a “city killer” that would probably annihilate between 100 and 1,000 times more people than an atomic bomb. “It will basically wipe out any of modern cities,” Hall said.

Is a hydrogen bomb hotter than the sun?
A hydrogen bomb, where a nuclear fission reaction compresses the fuel pellet instead, is an even more extreme version of this, producing greater temperatures than even the center of the Sun.
Can a hydrogen bomb destroy a whole country?
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.
Can you survive a hydrogen bomb?
You’ll need to shield yourself from the thermal and nuclear radiation, as you could die if exposed. However, you must find somewhere safe – you don’t want to be crushed in a building destroyed by the blast wave. Get indoors, and preferably into a reinforced bunker or basement.
What is hotter than lightning?
A bolt of lightning is 5 times hotter than the surface of the sun. One thing hotter is when gold atoms are smashed together by the Large Hadron Collider, but only for a split second. Another thing hotter is a supernova.
