I used to work for General Dynamics, the company that made the Phalanx. But
that is off topic.
I saw a show recently that stated the the US Army is switching to a
tungsten/plastic mixture for bullets to replace lead. They call it a green
bullet because it is more environmentally friendly. They claim that they
spend a lot of money cleaning up shooting ranges from the lead
contamination. That is probably true. However, I bet the higher mass for the
same caliber has something to do with the decision as well. Since it is
tungsten powder glued together with plastic, I bet the bullet brakes up to
powder upon impact. That means that all the energy is absorbed by the
target. It should still incapacitate you from the impact, even if you were
wearing body armor. Just speculation on my part. No armor would mean even
more damage than a normal round.
My father was a Marine for 25 years and from every source I have heard
depleted uranium is very toxic and yes radioactive. The gunners in
CH-53's have to wear special gloves when loading the rounds and while
firing, they are used in weapons like the GAU 2B mini gun and such.
Very unlikely you could buy any as it is a controlled material.
Wish I could have found about 4000 pounds of the stuff when I was casting my
keel bulb. With that density down in the bulb I could have had a higher
righting moment and saved about 2000 pounds in total weight. Encased in
lead it would have been safe too. The spot price for DU was about
$8/pound when I was looking. Way to high for the quantity I needed and the
paperwork requirement was outrageous.
OTOH, Iridium would have been even better but at $2400/pound I will pass.

You should read this
They can offer samples too, if you do paperwork
That's a somewhat contentious statement ! (Do you have newspapers
As a pragmatic approach (I'm not interested in the DU toxicity argument
today), the metal is safe and the oxide is toxic. However burning the
metal produces the oxide as huge quantities of breathable fine dust and
mechanically abrading the surface may do so too. You can safely own this
stuff, but it should either be plated or sealed into a glass vial. You
don't want to be handling it.
You have Bush as President. Johnny Appleseed has just been sentenced as
a terrrorist for posession of apple pips containing cyanide.
If you want some funky heavy metal, then go to a welding shop and buy
some TIG electrodes. These are tungsten, and look and feel as close to
uranium as you could wish for. Get the ones that are plain titanium,
not those with thorium alloyed.

What is depleted uranium depleted of?
I've always thought that this stuff is the byproducet of the nuke bomb
industry where the valuable U-235 is removed from the not valuable U-238
which isn't radioactive.
I'll also note that granite is radioactive yet we build buildings with it
Why isn't there an Ozone Hole at the NORTH Pole?
Actually, it is! As I recall, removed granite waste is a low-level
Banannas will also kick off geiger counters, I guess they are too commonly
used by the public to be classed though.
"California is the breakfast state: fruits, nuts and flakes."
Well...somewhere, in some secure storage facility, are dozens or hundreds
of white "bunny suits", gloves, masks, hats, and assorted clothing worn
by me, while working in the "hot lab". I was packaging _very_ low level
solid sources into test fixtures (for tuning medical nuclear imaging
scanners). Even the packing materials are in some "low level nuclear
waste" facility, even though the bags couldn't leave our hot lab if there
was _any_ detectable radiation level.
I have to try that tonight. The potassium, I suppose?
