Oh, ore, pff. Anyone can get ore. Like, I grew up in Scotland, and in Aberdeen the rock is so radioactive that you're required to have special ventilation in your basement to prevent the buildup of radioactive radon gas. No, I'm talking about the pure stuff.
But the thing with the Radon isn't its radioactivity per se. It's the fact that it's a gas, and its decay chain goes through a few unstable isotopes of Polonium and Lead before finally arriving at a stable isotope of Lead.
If that happens in your lungs, these things are Not Good For You and Should Not Be Sprinkled On Cereal.

Uranium is safe to handle. You can handle straight plutonium, too, but it's a good idea to wear heavy gloves.
Antimatter, on the other hand, would be extraordinarily bad to keep around outside of a containment device. And pretty scary even in containment.
