Update on geiger counter
I've been running the geiger counter nearly continuously for a year and a half--since December 1st, 2005. It's down today because we are going to build a cloud chamber at the Ryerson Astronomical Society meeting tonight, and I'd figure we'd have some other detectors there as well.
