The half-life of an atomic bomb is tens of thousands of years. Why can Hiroshima and Nagasaki survive now?

As an island country, Japan has a small land area, but a large population, and domestic resources are quite scarce, so it wants to plunder resources through aggression. Japanese militarism is deeply rooted. In the late World War II, Japan did not have the upper hand in the national battlefield and the Pacific battlefield. It is also impossible to lengthen the front, but Japan has no intention of withdrawing from the battlefield at all, which makes the United States very angry. In order to teach Japan a lesson,

The United States intends to land on the island of Japan and launch an attack on Japan to let Japanese militarism know that big countries are not easy to mess with. This time just happened to catch up with the success of the American atomic bomb test. In order to minimize its own losses, the United States decided not to land on the island of Japan, but dropped two atomic bombs on Japan. After appreciating the power of the American atomic bomb, Japan realized that if it did not surrender, the whole country of Japan would be in danger, so the Japanese emperor finally announced its surrender, and Japan's withdrawal from World War II represented the end of World War II.

1945 On August 6th and 9th, Hiroshima and Nagasaki, Japan were dropped atomic bombs by the US Air Force, which is the only record of human using nuclear weapons so far. Hiroshima and Nagasaki, once prosperous, suddenly became ruins. As many people know, with the explosion of the atomic bomb, a large amount of nuclear radiation will be produced. In many places, after a hundred years, no plants can survive. Then why did Hiroshima and Nagasaki come back to life long ago?

The first reason is that the two atomic bombs dropped by the United States exploded before landing, and a large amount of nuclear radiation was in the stratosphere. The second reason is that the two atomic bombs dropped by the United States produced very little radioactive material. The third reason is that Hiroshima and Nagasaki are close to the sea, and the sea will take away some pollutants produced by atomic bombs and purify them. So in fact, although Hiroshima and Nagasaki were destroyed by atomic bombs, they suffered little nuclear pollution, so they resumed reconstruction and began to live in just a few years.

Hiroshima is one of the best cities in western Japan at present. It stood up from the ruins. During World War II, two atomic bombs fell on Hiroshima and Nagasaki respectively, crushing the spirit of Japan. Actually, nuclear explosion and nuclear radiation refer to two things. If an atomic bomb explodes in mid-air, it will also produce nuclear radiation, but it will also bear shock waves. In this case, radiation will also exist, but it will disappear in the next moment and disintegrate quickly. But unlike nuclear radiation, it will gradually integrate with the land, and the harm to people is long-term. The atomic bomb used by the United States during World War II only exploded in the air, which is the first situation we talked about. Therefore, Hiroshima and the future will not be affected by nuclear radiation, and people can live and develop here with confidence.

World War II has already ended, and great changes have taken place in the countries that participated in the war at that time. At that time, China was the main target of Japanese aggression, but now it is not a backward country that was poor and weak in the past. We have become one of the few countries with nuclear weapons, and China has already risen from the decline of the past. But what has not changed is that China has always been a peace-loving and peace-keeping country and a big country. Although we have nuclear weapons, we will not rely on them to invade and oppress other countries.
