Why do vaporized people leave a shadow when the atomic bomb explodes?

Strangely, even today, Hiroshima and Nagasaki have not been attacked by atomic bombs for a hundred years, but today Hiroshima and Nagasaki are already crowded with people. In Japan, a country with a large population and a small population, Hiroshima and Nagasaki have developed quite well. 1945 is it a big lie that the atomic bomb attacked Japan? Or is the atomic bomb a fake?

In fact, in the year when Hiroshima and Nagasaki were bombed, that is, 1945, the Japanese began to rebuild, and in a few years, they got Hiroshima and Nagasaki back. And the nuclear bomb is a real nuclear bomb. At that time, the Japanese who were bombed by nuclear bombs did not die on the spot. Later, they all got many strange diseases, among which the incidence of leukemia was ten times higher than normal.

First of all, this is a theoretical value. In fact, this value will change according to the conditions of dropping the atomic bomb. What you may not know is that the atomic bomb explosion did not happen after landing. The atomic bomb exploded when it was dropped into the air, and its power was mainly aimed at air forces. Moreover, the atomic bomb at that time had just been successfully developed and its power was still relatively small.

The present situation of Hiroshima

Secondly, it is relatively easy for the two cities to clean up the pollutants left in the air by the atomic bomb explosion. As we know, due to frequent earthquakes in Japan, houses in Japan are not tall and easy to be demolished, while Hiroshima and Nagasaki are close to the sea, and pollutants will be blown away by sea breeze and waves. In addition, the half-life of nuclear pollutants produced by nuclear explosion is relatively short, and the radiation disappears relatively quickly.

Finally, the reason why the United States exaggerates to the greatest extent that the places attacked by atomic bombs do not grow grass and people can live for a hundred years is mainly to show their strong military level and play a role in shocking the world. Japan admitted it in the hope that the international community would lighten its condemnation because Japan was attacked by an atomic bomb. But in any case, the influence of atomic bombs on Hiroshima and Nagasaki still exists. Although Hiroshima and Nagasaki can still live and live, the lessons left to them may be much longer than the half-life of nuclear radiation.
