But you see, they aren't equaly dangerous. (lead and DU)
First of all, those researches are questionable, but I won't go there, since it's kindof political.
But even if they are equally dangarous when testing them in a lab or looking at data sitting behind a desk, but out there in a war zone the thing is:
-people aren't afraid of lead particles-
So, the psychological effect DU has is HUGE. It's not enough that you endure all the stress of bombs exploding around you and bullets fly by your head, you add to that a constant sensation that some evel radiation is eating you inside. And that alone will kill you faster that any slow acting poison or radiation out there. So what? You educate people in the field. Don't think so. You can't force the genie back in the bottle.
What ever the reasons, the fact remains that people die faster and in greater numbers in areas exposed to DU, than in areas exposed to other ammo.
