As in "The uranium's radioactivity had been depleted"

Secondly, some facts on Uranium link
From this link we learn that
On a scale arranged according to the increasing mass of their nuclei, uranium is the heaviest of all the naturally-occurring elements (Hydrogen is the lightest). Hydrogen will blow about in the air. Uranium, being heavier than lead will not. Well, unless you put wings on it, and flap 'em real hard like.

From same link we also learn that "It occurs in most rocks in concentrations of 2 to 4 parts per million and is as common in the earth's crust as tin, tungsten and molybdenum. It occurs in seawater, and could be recovered from the oceans if prices rose significantly."
That's right, it's always been here, it doesn't originate from some neoconservative stronghold beneath the pentagon. and you'd be more apt to get radiation poisoning from swimming in the ocean, than say, walking through baghdad.

Well, those are facts. This here innner nets a big ol' place, why don't you step outside your fellow traveler sites a bit, and look at the real world? I mean, only if you want, nobody's forcing you.
