And yes, this sample is radioactive.

But we did speak to professionals about how to properly handle this stuff, so we're taking

all the necessary precautions, but you know, don't try this at home.

Now the rest of this ore is just regular rock, plus some elements like lead, thorium and

bismuth that the uranium is slowly decaying into.

And this, this is a Geiger counter.

It's measuring the levels of radioactivity around it.

But what's setting it off isn't the uranium. It's the lead thorium, bismuth, all that stuff

we were just talking about.

And in case you're wondering, this is considered weakly radioactive, but we don't want to be

hanging around it all day.

Now this small piece of rock is called uraninite.

This actually contains a much higher concentration of uranium.

Think of it as a bunch of uranium just packed tightly together.
