Can people still live in Hiroshima, Japan?

Although there was a nuclear explosion over Hiroshima in Japan during World War II, it is still habitable after so many years. The main reasons are as follows.

First of all, Japan is an island country, and earthquakes, typhoons and floods often occur. It is for this reason that the nuclear radiation here is gradually blown away, and many of them are blown away by water and wind. Under such long-term effects, there is no nuclear radiation here.

Secondly, Japan is a relatively small country, so the Japanese can't wait to move in when there is almost no nuclear radiation, and they are not very worried, because people here have not been affected yet, so we have to say that the frequent occurrence of such disasters is helpful to Japan.

Finally, the atomic bomb dropped on Hiroshima formed dozens of kilograms of fission radioactive materials, most of which were scattered with the wind or washed away by rain, and the rest were scattered in the area of several hundred square kilometers near Hiroshima, with an average of less than 0.00 1 g per square meter, which was not fatal or even pathogenic, so Hiroshima could still survive after the atomic bomb explosion.
