With the destructive power and the influence of radioactivity, nuclear weapons have become the most feared destructive weapon ever. Two atomic bombs dropped on Hiroshima and Nagasaki in 1945 marked the end of World War II. However, the horrors that it left were never forgotten, an unprecedented destructive power plus the influence of radioactivity caused the atomic bomb to become the most terrifying destructive weapon from so far.
After World War II, the arms race between the US and the Soviet Union in the Cold War began from 1945 to the end of the 1980s. Both sides spent huge investments in research and production. nuclear weapons. And since then, the threat of nuclear war has always been lurking.
After the cold war, the Soviet Union collapsed, relations between the US and Russia improved and the two countries pledged to cut nuclear weapons. A series of treaties are signed, in which the main objective is to reduce and limit the nuclear warheads owned by each country. But not because of that, the threat from nuclear war ends, countries like North Korea continue to test nuclear weapons. The US, Russia and China can also attack any target in the world with nuclear warheads. The weapon of destruction had many different changes to the two bombs nearly half a century ago.
The atomic bomb, also known as the nuclear bomb because of its destructive power, originates from these tiny nuclei. There are two basic ways for nuclear energy to be emitted from atoms: fission and nuclear fusion. In it, fusion is the power to regenerate from solar energy, and fission is the destructive power used in atomic bombs.
While uranium atoms typically need 700 million years to decay, an impact from free neutrons will make the nucleus unstable and possibly decay immediately. When uranium atoms receive free neutrons, it decays into two lighter isotope atoms and releases about 2 or 3 new neutrons. This process simultaneously emits gamma rays that radiate and release energy.
