How many years did it take to recover after the nuclear explosion in Hiroshima and Nagasaki?

Hiroshima and Nagasaki quickly completed urban reconstruction within five years after the nuclear explosion.

Twenty years of reconstruction is possible. After all, there will be a lot of pollution and radiation from nuclear explosion, but the urban reconstruction took only five years to complete and trees were planted. So far, it is not clear whether this beautiful city has suffered a nuclear explosion.

Nuclear explosion will pollute, but it will dissipate by itself, but the process is a bit slow, and it was an empty explosion at that time. Considering the terrain and weather factors at that time, nuclear radiation was not as serious as expected.

Sequelae of Hiroshima atomic bomb:

The Hiroshima atomic bomb exploded 600 meters above the ground. After flashing lights, sound waves and mushroom-shaped smoke clouds, fires and smoke enveloped the whole city.

140000 people died in Hiroshima atomic bombing, many of whom died of nuclear radiation weeks or even months after the explosion. After the explosion, many survivors suffered from radiation sequelae, including cancer, leukemia and skin burns.

Extended data:

1in the summer of 945, Japan was defeated, but Japan's crazy resistance in Okinawa and other places led to a large number of allied officers and soldiers casualties. At that time, the U.S. military had formulated the "Crown" and "Olympic" action plans for landing in Kyushu and kanto region.

In order to protect the lives of allied officers and soldiers, force Japan to surrender as soon as possible, and also to contain the Soviet Union, US President Truman and senior military officials decided to drop atomic bombs in Japan to speed up the war process.

The US military chose Tokyo, Kyoto, Hiroshima, Nagasaki, Kokura, Shinji and other cities in Japan as alternative targets for dropping atomic bombs.

Earlier, the United States, Britain and the Republic of China issued the Potsdam Proclamation, urging Japan to surrender. On July 28th, the Japanese government refused to accept the Potsdam Proclamation.

On August 6 and 9, the US military dropped atomic bombs on Hiroshima and Nagasaki, Japan, causing a large number of civilian and military casualties.
