In this article we’ll discuss Why can you live in Hiroshima but not in Chernobyl. Both cities suffered a major atomic disaster, where radioactive fallout was released. The uranium fissile atomic bomb, little boy, was detonated in Hiroshima with a yield of 15 kilotons of TNT. Chernobyl's uranium fissile reactors produced 3,200 MW (megawatts) of thermal power, — also using fissile uranium. As you know, the reactor blew up.

If you don’t feel like reading I’ll tell you the exact same story in this video here.

Hiroshima is now well and prospering but Chernobyl remains uninhabited. So what’s the difference between these disasters?

Chernobyl: still remains radioactive and uninhabited
Hiroshima is a prospering city

The short answer is the amount of radiation. DOH! obviously. But let’s look into a deeper answer.

Detonation type

The first reason is the type of detonation. The atomic bomb in Hiroshima was detonated hundreds of meters above ground to maximize its yield. Upon detonated the bomb is completely vaporized and therefore the radiation is distributed in a huge area by the blast.

That is why wind greatly affects the radioactive spread in an atomic bomb, as shown below;

Wind was not an important factor of the Chernobyl explosion , because it wasn’t nearly a powerful explosion as the little boy atomic bomb, furthermore the explosion occurred at ground level. While Chernobyl released plenty of radioactive fallout in the air, the pressure of the tank caused a ground level weak explosion. It left huge chunks…
