It is said that the area where the atomic bomb exploded cannot be inhabited for at least 100 years. Why do people live together when Hiroshima and Nagasaki are only ten years apart? Moreover, after decades, the vegetation in these two cities is very lush, and the Japanese still grow fruits and vegetables here. Why? Nagasaki and Hiroshima suffered atomic bombs of 20,000 tons. Now the maximum single quantity can be 2 million tons. The lethality of nuclear fission of atomic bombs is really great. First, strong light radiates shock waves through radioactive materials. When nuclear fission occurs, the best way is to hide underground, in a relatively hidden place, which means that the destructive power of nuclear fission is mainly on the ground. After Hiroshima and Nagasaki suffered atomic bombings, nothing grew and life became extinct.
First of all, many of us have the impression that if this area is bombed by atomic bombs, it will definitely become a barren land, and the resulting radiation will make all animals and plants unable to grow, and even the surviving creatures will mutate. But these views are determined by the amount of radioactive material in the atomic bomb. The atomic bombs dropped on Hiroshima and Nagasaki at that time were named? Little boy? And then what? Fat man? These two atomic bombs don't have much radioactive material, which is nothing compared with the No.3 reactor of Fukushima nuclear power plant. The Fukushima nuclear power plant has 90 tons of mixed oxide nuclear fuel, and the radioactive material in the nuclear reactor is thousands of times that of these two atomic bombs.
Secondly, the atomic bombs of Hiroshima and Nagasaki exploded in the sky. Although they also released a lot of radiation, during the explosion, some of these radioactive substances rose into the air with the heated air. Is this what we saw? Mushroom cloud? After that, these radioactive materials were taken to the stratosphere and spread to every corner of other regions. In this way, the radioactive materials falling on Hiroshima and Nagasaki will be reduced by more than half.
In fact, the casualties caused by these two atomic bombings are mainly shock waves, fires and high radiation caused by huge energy. In the following decades, some Japanese people lived here and received radiation, which led to cancer, but the number was not much. From this point of view, living here is completely acceptable.
Finally: Hiroshima and Nagasaki were bombed by atomic bombs for more than 70 years. After the nuclear explosion, some radioactive dust fell into these areas. Also, with the rain falling to the ground, the soil in Hiroshima and Nagasaki has changed. In the past 30 years, there have been no plants to grow. Now the radioactive materials in the soil have passed the decline period. Japanese people not only live here, but also grow food, vegetables and fruits.
In fact, the nature of atomic bomb explosion and nuclear power plant accident is different. There was no huge explosion in the nuclear power plant leakage, and most radioactive materials stayed nearby and would not spread, so the radiation concentration in the nearby area was very high, as was the case with the Chernobyl nuclear accident and the Fukushima nuclear accident. Residents in the vicinity of more than ten kilometers have all been evacuated, and there will be no residents living nearby unless the amount of radiation is reduced.
Hiroshima today
Actually, one more thing. It was not until Japan was a small country with a large population and few places to live that Hiroshima and Nagasaki had to live.
