Where to get depleted uranium?


U235
Correct.
And the basements of houses built on granite fill up with Radon. There's plenty of radioactive fallout from the 50s, the CO2 in the air is has Carbon-14, water has tritium, potassium-40 occurs in natural potassium, which is everywhere, including bannanas and people. Space is full of natural fusion reactors, the earth has Van Allan belts, recently we got hit with a massive cosmic ray burst, etc.

Gold and platinum are denser than either of those, plenty nifty, and more practical to own.

Not true, although it is denser.

Get in a war with the US or NATO and the military will deliver it, no charge even!

Depleted uranium is radioactive and anyone uncovering a shell made from it gets radioactive poisoning, bad stuff...

False nonsense.

Depleted uranium is a mild alpha emitter. Your skin will stop the alpha particles. Breathing in particles of DU is a different matter, but just picking one up is not likely to cause a problem.

Depleted uranium is used as counterweights in the control system of many aircraft. It is usually re-cycled when aircraft are junked. I also saw a pair of DU penatraters from some tank rounds at an Army Surplus store, but they wanted a young fortune for them. Far more than the metal content was worth.
What in the world do you want to do with it any way? Its difficult to machine, very hard, also its pyrophoric. Meaning the hot metal shavings have a tendence to burn when exposed to the O2 in the air. Breathing the fumes from this can be deadly, as others have mentioned DU gives off alpha radiation, which is relatively safe, until it gets inside your lungs.
