nuclear weapons are the most powerful weapons developed in the history of mankind. When it was initially developed successfully, some participating scientists lamented: This will be a dark day in human history. In terms of the process of discharging energy, nuclear weapons can be divided into atomic bombs, hydrogen bombs, and three-phase bombs.
The horrible power of nuclear weapons
Ordinary hydrogen bombs are based on atomic bombs and are coated with a layer of thermonuclear material. The energy release process is fission-fusion, and the two reaction processes will release More energy, which is why hydrogen bombs are much more powerful than atomic bombs. Therefore, hydrogen bombs can also be called "biphasic bombs."
As the name suggests, the "biphasic bomb" contains two reaction processes, and the three-phase bomb contains three reaction processes. It is a layer of depleted uranium (uranium 238) outside the ordinary hydrogen bomb, and the energy release process is fission- Fusion-fission, which doubles the power of ordinary hydrogen bombs, and because of the large number of uranium-238 fragments produced by the explosion, the sustained lethality is much higher than that of atomic bombs and ordinary hydrogen bombs. If a place is bombed by a three-phase bomb, it is impossible to imagine that it will become a gathering place again in decades like Hiroshima and Nagasaki.
Hiroshima has been restored to life
The power of the three-phase bomb is so powerful, some scientists thought, since hydrogen bombs can be put on a uranium-238 "vest", why not Try to replace it with a more powerful shell? So in 1950, a scientist named Leo Szilard proposed the cobalt bomb. To put it simply, the uranium 238 shell of the three-phase bomb is replaced with a cobalt 59 shell. The principle is the same as before, which is to use the high-speed neutron stream produced by the hydrogen bomb explosion to bombard the shell, causing the cobalt 59 to react and become the radioactive isotope cobalt 60 .
Hydrogen bomb
From the point of view of the instant explosive power, the cobalt bomb is not larger than the ordinary three-phase bomb, but its sustained killing ability is much greater than the latter. Cobalt 60 is very dangerous. When using it in industry, be extremely careful and take strict protective measures. Usually 3 grams of cobalt needs to be shielded with half a ton of lead , and a cobalt bomb usually uses cobalt 60. Tons to calculate. Imagine that if is a large-yield cobalt bomb detonated in the stratosphere, pollutants can travel throughout the earth’s atmosphere. The half-life of cobalt 60 is very long, and the decay process has high penetration and long-term continuity. The gamma rays will damage biological DNA and cause the extinction of almost all life on earth in a short time.
Cobalt 60 has extremely strong radioactivity
also because of its power, so it only exists in theory so far, mankind has not actually manufactured this weapon— —No one wants to die together. But from a technical point of view, manufacturing cobalt bombs should not be impossible for those big countries.
Countries are competing in the field of hypersonic weapons
It is worth noting that, although cobalt bombs are fierce, it is not the only thing that may destroy mankind. Ordinary nuclear weapons, as long as the number is sufficient, Just as it can destroy mankind, more powerful weapons will be developed in the future that can destroy mankind and even the earth. Therefore, from a fundamental point of view, what all countries need to do is to strengthen their capacity for self-discipline, and they cannot engage in an arms race unscrupulously for their own benefit. The shadow of the US-Soviet hegemony for all mankind has not yet completely dissipated. But now, the arms control agreement between the United States and Russia may not even be able to keep the "single seed" of the "New Strategic Arms Reduction Treaty". A new round of arms race represented by hypersonic weapons and space weapons has already "gained momentum." To be sent". (微奇)
