The radioactive material they sell you is probably in the form of uranium glass marbles. Also known as vaseline glass. It is glass that has tiny amounts of uranium naturally infused in it. As a side affect of this, it kind of glows green in natural light and bright green under UV. I have a container of 100 such marbles on my desk. They are harmless, I think you'd have to gather more than a million of the marbles in one place to even have a potential personal risk. The radiation level and mineral is far far below any safety or security considerations.
