How To Make A Geiger Counter

Here's a very good and fairly simple Geiger Counter circuit that you can make which I found online. I did make a few modifications to the schematic shown at Jon's website below, which are shown in this video. Monitor background levels of radiation, or test rocks and other objects for radioactivity. Enjoy the video!
