It's fairly amazing you can see that with a conventional geiger at all -- low energy gammas just don't do much with gas. And even a big exit sign isn't all that loud here -- had there been another source there, that peak would have been tiny in comparison to the rest of the plot. I guess I'd have to think the mechanism was beta hits glass and becomes a somewhat lower energy photon, which then can get through - the window on my Gamma spec isn't super thin itself, but is Be. But it is interesting that the "experts" were wrong. I wasn't terribly surprised to see this on the most sensitive thing I've ever owned, but a geiger counter is fairly amazing.
Yeah, it's raining now, so no takee scope outside to test. Where you live I guess "rainy season" has a whole new meaning. We're getting a lot more than usual here, but that's probably just the usual unpredictability of our mountain weather, about which we say "if you don't like it now, wait a few minutes". It's nothing special to see snow out of a clear sky, or walk just a few feet from a torrential downpour to completely clear around here. Though it has been usually bad for solar power the last couple weeks.
I left new member registration enabled overnight so a guy who asked me could register and even set him up with an account, and this morning -- he's not there, but two spam bots were, and one had already started trying to sell drugs on the board. Too bad for them - gone now, and the IP address they rode in on. And the drugs weren't interesting anyway. Makes me want to tune up the rifles and go hunting for two legged predators. A nice gut shot on a spammer so it takes them a long time to die sounds about right.
Posting as just me, not as the forum owner. Everything I say is "in my opinion" and YMMV -- which should go for everyone without saying.
