I'm trying to do a demo for a class report on radioactivity and am looking for different materials I can bring as examples of radioactive samples in everyday life. I was told that the mantles for Coleman lanterns used to have thorium in them. I can't seem to get my hands on any of these though. What other items, that we possibly use everyday, give off measureable levels radioactivity. I have a digital geiger counter for use in class. It says it can read alpha, beta, and gamma rays.
Re: Where can I find some everyday items that are radioactive?
