Uranium is pretty neat stuff, I consider myself a fan. I’ve always wanted some "yellowcake", so when I saw an opportunity to buy some, along with uranium dioxide, uranium metal, and thorium dioxide, I couldn’t resist. It’s all pretty neat stuff, but other than the chunk of U-238 metal, it’s all finely powdered, and exactly the sort of thing you very much do not want to get inside your body. If you manage to breathe some of it in, it will settle to the bottom of your lungs, and stay there for the rest of your life. When it comes to radioactive materials, that’s very much a bad thing.
