What is a hydrogen bomb and what is its destructive power?

in #nuclear7 years ago

Used during the Cold War by the United States and the former USSR, it has a devastating power far greater than the atomic bomb and could completely destroy a city like Paris.

North Korea announced again on state television that it has carried another test with a nuclear hydrogen bomb shortly after a 6-degree earthquake occurred on the Ritcher scale in the northeast of the country, possibly as a result of the atomic test.

The event has provoked the immediate reaction of rejection by several countries such as Russia, Spain, Italy, Germany, India and international organizations such as NATO. In fact, NATO Secretary General Jens Stoltenberg said that the nuclear test "undermines regional and international security" and urged Pyongyang to respect its obligations and abandon its nuclear weapons and ballistic missile programmes.

The condemnation has been unanimous and categorical on the part of several countries and agencies. This is clearly a matter of concern to the international community and is seen as a challenge to stability. But the question is, what exactly is a hydrogen bomb?

"An H-bomb" is what we call a thermonuclear bomb. H "refers to hydrogen, a gas used for hydrogen. Basically, this bomb triggers a specific nuclear reaction called "fusion". When the bomb goes off, the hydrogen atoms fuse together and release a huge amount of energy. The problem is that triggering the fusion also requires a huge amount of energy at startup. That's why an atomic bomb ("A-Bomb") can be contained inside a bomb of this type that explodes first to trigger the fusion,"says Maxime Heckel, an engineer at the French School of Engineering, ENSIIE.

The atomic bomb (used against the Japanese in Hiroshima and Nagasaki at the end of World War II) uses only radioactive materials (uranium-235 and plutonium) to trigger a nuclear reaction called fission. Fission releases less energy than fusion, so the atomic bomb is somewhat less devastating than hydrogen,"adds Heckel.

The hydrogen bomb was used in the past, especially by the USSR and the United States during the Cold War. The largest was the Tsar bomb (used by the USSR). It was a 50-megaton TNT hydrogen bomb (a unit to calculate the energy released by a bomb. To get an idea, the bombs dropped in Nagasaki and Hiroshima had 13,000 tons of TNT. A hydrogen bomb could destroy a 30-40 kilometer radius. If you drop a bomb like that, you could easily destroy a city like Paris completely.
