As we all know, the United States dropped atomic bombs on Hiroshima and Nagasaki in Japan at the end of World War II. A total of hundreds of thousands of Japanese civilians were killed on the day of dropping. The international community was shocked by this. Since then, it has been concerned about the atomic bombs. Strict regulations are made for the use of. Although the lethality of nuclear weapons is amazing, the military powers still have not stopped their research in the field of nuclear weapons to enhance their national defense capabilities and avoid nuclear threats from other countries. However, the actions of the United States and Russia withdrawing from the Intermediate-Range Nuclear Forces Treaty in 2019 have made countries around the world once again feel the threat and fear posed by nuclear weapons. What is the kill range of nuclear weapons? How far do we have to be safe when the nuclear bomb explodes?
Everyone knows that nuclear weapons have a very strong lethality, but they don’t know that their lethal range is very limited. Generally speaking, the scope of impact of nuclear weapon explosions is mainly affected by two factors, namely the equivalent of nuclear bomb and the height of explosion, among which the equivalent of nuclear warhead The bigger, the stronger the lethality. In the past, someone has performed a nuclear bomb explosion simulation. If a nuclear warhead with an equivalent of 150Kt explodes over a city, more than 240,000 people will die because of the shock wave.
After a nuclear bomb explodes, there are mainly 4 destruction circles. From the center of the explosion to the outside are nuclear fireballs, early nuclear radiation, air-blast shock waves and thermal radiation. The farther away from the center, the less lethality is. In addition, when it comes to nuclear explosions, everyone will inevitably think of nuclear radiation, but countries that use nuclear bombs to strike generally choose high-altitude detonations, and the radiation range of nuclear bombs that use air explosions is also limited. Because a ground-touching explosion is likely to lead to the destruction of mankind and even restart the earth, the "nuclear winter" that people fear most will not appear because of an air-explosive nuclear bomb.
From a comprehensive perspective, if you encounter a nuclear weapon attack, of course, the farther you go, the safer you are. Taking an air-burst nuclear bomb with a nuclear warhead equivalent of 150Kt as an example, the radius of the four explosion circles of nuclear fireball, early nuclear radiation, air-burst shock wave and thermal radiation produced by this explosion are 450 meters, one kilometer, 3.7 kilometers and 5.3 kilometers, respectively. This means that if you want to be immune to the explosion of the nuclear bomb, you must be at least 10.5 kilometers away from the explosion center. However, when a nuclear explosion really comes, there is still so much time for you to calculate and consider, and you may not know the bomb equivalent of a nuclear bomb. Therefore, the safe distance of a nuclear bomb explosion is actually unable to give an accurate answer. It depends on the specific situation. In short, the farther away from the explosion center, the better.
Although there is a certain possibility of escape when a nuclear explosion comes, it must be clear to everyone that the chance of a successful escape in a nuclear explosion is very small. We look at the statistics of hundreds of thousands and 200,000 deaths. It is very numb, because it has never really happened to us. No country can stand alone in a nuclear war, and pray that nuclear weapons will never come in handy.
