Cloud chamber & Alpha particles

We had Dr Alexander McKinnon in school today talking about types of radiation from space. He had a really informative presentation about radiation and particle research and he even brought over his cloud chamber to demonstrate the alpha particles produced from a welding rod. We could see the cloud tracks made in the chamber as each particle passed through it. We also managed to see a few background beta particles as well.
