why is that,atomic bombs can kill many people but can't totally destroy concrete buildings?

Answer 1

If the concrete building is in the fireball it will be largely consumed by the intense heat. Whatever remnants there are of it will be useless.

People are very limited in what they can withstand structurally. We can't take too much heat, and we don't withstand high impacts very well. And, as someone has noted, we can suffer radiation poisoning.

Most of the Japanese who died at Hiroshima and Nagasaki were killed by the heat of the atomic explosion and its effects, or in the fires which burned the city afterwards. A large number suffered radiation poisoning and many of those also died. An atomic explosion is complex, with many effects. People died from blast effects as well.

Concrete structures can withstand heat up to a point but are greatly affected by blast. Outside the fireball portions of a concrete structure could survive reasonably well. They did not generally shield occupants from the intense heat, and many people inside concrete buildings died from heat or fire.

Answer 2

Think of it as this way you put an adobe brick and a pumpkin into a furnace at 2000 degrees. What happens? The pumpkin evaporates and the adobe brick hardens it is all due to the properties of what the items are made of. So a fragile human mainly made up of carbon and water against a steel and concrete building what do you suppose will happen. Then, even as a person if you are far enough from the initial blast but not far enough from the radiation fall out then the radiation poison and heat will get you.

Answer 3

It will be just like Iraq all over again. What is happening in Iraq will exactly happen in Iran if it's military is totally destroyed. Insurgency and guerilla warfare will surely take place. Is the U.S. prepared for such a scenario?. Furthermore, Iran shares its border with both Syria and Russia. I'm sure that the Iranian insurgents will be eventually supplied by these neighbors with weapons across the border to kill American troops. Then what?. Bomb Russia?. Oh boy, I love to see that. It will be real fun.

Answer 4

Because atom bombs are like all bombs.
They do most of their physical destruction
from over-pressure in the atmosphere.
And concrete can absorb a tremendous
amount of overpressure, while everything
else around it crumbles.

Answer 5

Its mainly the radiation given off that kills people. Additionally, the human cannot take as much an impact as concrete.

Answer 6

The radiation will kill people but only the blast from the bomb will actually do structural damage.
