America has bombed Iraq with weaponry that will pollute the soil and underground water with radiation for thousands of years. It also enhances its bombs with spent uranium to cause even greater harm to the people and the environment.

I supose that what is referred to here is the "spent uranium" used in some types of anti-tank shells. Note that, as far as I know, only tanks fire shells with "spent-uranium" (to make them more dense, to more easily penetrate armor). It is not used in bombs, there's no point.

The radiation level is very low. Naturally occuring radon gas in the ground is more dangerous.

Depleted Uranium is used in Fission, Fusion, Fission nukes.
H-bomb, in other words.
