... http://www.cosmicrays.org/muon-PM1_1.gif ;-) Here is my short update: I tested the detector last weekend again with the uranium glass marbles, but I didn't...
Hannes... I also bought some of the uranium glass marbles. I found that if they were placed close to my detector, the recorded count just about doubled from...
... Hannes, Thanks for the post. Too bad about the marbles. I haven't yet purchased them but I still might because they are still pretty cool. Best regards, ...

... Hi John! Thanks for the info! As far as I know, those marbles are mostly alpha emitter, right ? And I assume the window of the Aware GM tubes is thin, so...
... John, Overall, it looks quite good and should work well for you. Let me make a few observations: - I've used only 10MOhms in series with the +HV supply and...

Hey Mike Can you say exactly what time the event occurred, and the percentage drop. I may have a negative co-relation event here in Bristol, UK. Also, can you...
I posted two jpegs earlier. DSC00101 was taken April 13 at 11:57am, black line. DSC00097 was taken April 17 at 12:39pm, black line. The drop on the 13th is...

Hi John, Did you look at the uploaded jpeg's under "Files" to see if any of your data matches? I uploaded another jpeg today of Sunday's drop. It started at...
I uploaded another jpeg screen shot of the ambient drop in radiation for Sunday morning the 18th starting at about 9:35am and ending at about 10:20am Arizona...
Hi John. I've got a suggestion. Instead of taking a photograph of your screen and then rendering in into a .jpg why don't you make a Screen Shot of it. To do...
