  The geology building at Colorado School of Mines (a few miles west of Denver) used to have a display case in the main hallway with a Geiger counter running 24/7, and posters explaining what different spikes meant (ie, uranium decay made the needle move to such-and-such number). Sometimes I'd stand in the hallway between classes and watch. It was never more than about 15 seconds between decay events.
