Uranium-235 has a half-life of up to 700 million years! Why did people live in Hiroshima so soon after the atomic bombing of Hiroshima, Japan, and the Chernobyl accident is still a "ghost town"?

The damage of nuclear radiation to the human body cannot be counted, it is safe in a stable temperature, as long as there is a violent explosion, nuclear radiation will spread, and it will be fatal to human beings and even the world.
Chernobyl and Nagasaki, two places that suffered from nuclear disasters, are now a ghost town with no people, and even after so many years, there is still a high level of radiation.
At that time, Chernobyl was a vibrant city, but after a nuclear accident in 1986, it was completely in ruins.
At that time, the No. 4 reactor of the nuclear power plant suddenly caught fire and exploded, and a large amount of radioactive materials were thrown into the air, and the rain washed them down, polluting the land and groundwater in a radius of dozens of kilometers.
Scientists have found that Chernobyl buildings have even been "eroded" by radiation with countless small holes, and those radioactive particles drift in the air with the wind, gradually corroding anything else.
At that time, the situation was very serious, and if a person was exposed to radioactive materials for a long time, there would be a series of problems in the body, and then death.
For the safety of the people and future generations, the local government can only evacuate nearby residents to a safe place, which is why Chernobyl has become a "dead city".
Even after all these years, Chernobyl is empty, even the plants have stopped growing, and now there is no living creature in sight, only silence remains.
Why, then, did Chernobyl still have no vegetation, but was able to rebuild Nagasaki in Japan after the atomic bombing? Aren't both contaminated by nuclear radiation?
In order to gain the initiative in World War II, Japan simply carried out a sneak attack on the United States, and blew up Pearl Harbor without the knowledge of the US military.
At that time, the United States could not swallow this breath and began to fight back, which also became a turning point in World War II.
On August 9, 1945, the U.S. military dropped an atomic bomb codenamed "Fat Man" on Nagasaki.
Although the explosion caused heavy casualties, the radiation released by the atomic bomb quickly attenuated.
The main reason is that the amount of uranium and plutonium fuel dropped by the United States is not too much, only 6.4 kilograms, which is much less than the 8 tons of radioactive material leaked from the Chernobyl nuclear power plant.
The atomic bomb exploded in the air and would have polluted the ground and underground much less, while Chernobyl had a leak on the ground, and some radioactive materials were mixed with the groundwater, so it would lead to a large area of contamination and a lot of contaminated substances.
In addition, Nagasaki is geographically close to the sea, and the radioactive materials produced by the explosion at that time were in the air, and some of the nuclear materials were carried away by the sea breeze and seawater.
In addition, Nagasaki is an island, and some of the radioactive dust is carried away by the sea and sea breeze. Chernobyl's inland geography allows for the accumulation of pollutants, which is why Japan has been able to recover its cities in a short period of time.
I have to say that Japan is somewhat lucky, and although the site of the explosion has been built as a tourist attraction, it is not recommended to visit it.
Because there are few radioactive materials in nuclear contamination, but there may still be trace amounts of radioactive materials, for the safety of human beings, it can be avoided if it can be avoided.
For Chernobyl, Japan was lucky, but after the disaster, the two countries also urgently evacuated the crowd to prevent more people from being irradiated by radioactive materials.
Life is precious, and I hope that all countries will understand this truth and avoid the use of nuclear weapons, because the cost is too great to allow history to repeat itself.
