@AnguaDelphine The biggest impact of DU shells (excluding the impacts of the usual delivery mechanism) is actually just bog-standard Toxic Heavy Metal, not radiation. So it's basically just "lead, but brittle" (Not saying it's not a terrible idea to use it as a projectile, for numerous reasons, just saying that most of the badness is a very different beast than what most people think of as "uranium")

After the U235 is removed, "depleted" U238 on its own is "practically stable" to the point it's not-infrequently used as radiation shielding in place of lead, or for things like elevator counterweights. As long as you don't lick it or sleep propped up against it for years on end, you'll be perfectly fine.
