The uranium glass definitely showed a noticeable increase in CPM vs background, thanks!

Is Lead-210 a good test source?

My kit powers on and I get random beeps. I have a Lead-210 test source that we used in a cloud chamber with great results but the Geiger counter does not register anything when near the source. Is this not a good test source?
