(from the documentary web site) "Instead, the documentary exposes the White House and US State Department's hidden agenda in the Gulf as well as the Pentagon's use of radioactive ammunitions made of uranium 238."
It's not a secret that they use ammunitions made of U238, otherwise known as "depleted uranium". It's basically what's left over after the more useful U235 is taken out. It's a very heavy metal, twice as dense as lead and is used in munitions meant to pierce armor.
It's also used in civilian aircraft, and it's used to transport radioactive materials because it absorbs gamma radiation better than lead.
It is lightly radioactive, but almost all the radiation it produces is alpha or beta particles. It is dangerous if you find it IN your body; alpha particles are stopped by skin, and beta stopped by clothing. But if you find munitions inside your body, chances are you have a much worse health risk at hand.
It also produces a light amount of gamma radiation, but no more than you find in the background. DU is "60% as radioactive" as U235 but the 40% it's missing is the highly dangerous gamma particles.
It's not surprising that folks have pounced on emotionally-laden terms like "radiation" and "uranium" to produce scare pieces. Some will say that it's dangerous because if exploded it can be airborne and breathed in. That is the worst danger, I think, that is a legit concern. But you also get a dose of inhaled alpha particles if you smoke cigarettes, and the battlefield is not exactly a no-smoking area. It's dangerous by design.
