Hiroshima and Nagasaki, which were bombed by atomic bombs, all said that people could not live. Why do so many people still live there?

Although it was bombed by the atomic bomb, the ecological environment is very good now, and it has even become a tourist attraction. Moreover, Nagasaki is Japan's heavy industry base, and economically developed areas will naturally attract people to live.

At the end of World War II, the United States dropped two nuclear bombs on Japan to show how terrible this weapon was. Over Hiroshima and Nagasaki, Japan, nuclear bombs exploded, instantly devouring 20 million Japanese. No wonder people call it a destructive weapon, the most powerful weapon.

However, the reason why Hiroshima and Nagasaki have recovered so quickly is that the buildings in Hiroshima and Nagasaki are relatively primitive and people are naked. As we all know, nuclear explosions are generally divided into "air explosions" and "ground explosions". Air explosions are easily triggered by shock waves, resulting in a larger destruction radius and stronger destructive power to surface objects.

A large number of casualties and most ground buildings in Hiroshima and Nagasaki were destroyed after the nuclear explosion, but there is a characteristic of explosion in the air, which is shock wave and photothermal radiation. The nuclear radiation produced by the explosion is very deadly, but the remaining nuclear radiation is very small.

At that time, although Hiroshima and Nagasaki suffered directly, the residual radiation produced by the nuclear explosion did not reach a high concentration. A small amount of radioactive dust affects rainfall and ground precipitation, forming "black rain", which will only increase the content of radioactive substances in the soil. Subsequently, the United States confirmed that the radiation caused by the atomic bombings in these two cities did not increase much.

Although Hiroshima and Nagasaki were in ruins after the American atomic bomb attack. People resent that the long-term war aggression led to the collapse of Japan's economy, but in the 1950s, Japan entered a period of rapid development and rose rapidly.
