I am wondering if you had a chance to look at and critque my 5 web pages on "Monitoring Muons on the Surface of the Earth" I am interested if my statistics are correct and if there are any flaws in the setup of the 2 geiger counters and C-box. The most obvious experimental result is that the muon count / hour does change dramatically from vertical to horizontal and that there are peaks several times a day and they are above 95% reliability. Perhaps you or one of your engineers or experienced customers can review the website. Thanks again for any help you can provide.

Here's James's great Muon website:
Monitoring Muons on the Surface of the Earth
We now sell a triple coincidence box (Triple C-Box $129) for use with three RMs to plot Electromagnetic cascades in lead for generation of Rossi Curve.

Over a year ago, I purchased 2 RM-80's, a coincidence box decoder, plus software. I use my muon detector every day with an old 486 Dell that has run almost continuously since January 12, 2001.
My daily corrected muon counts show very good variability, and this variability allows me to study muon counts in relation to other data I am collecting about the Sun's behavior and the Earth's magnetic field.
My question has to do with neutrons. You offer equipment for detecting neutrons. I'm wondering whether that equipment could be used to detect the small variations in the background neutron count. I live at 43.15 North and 71.89 West, with an elevation of 630 feet and a cutoff rigidity of approximately 1.5 GV. The equipment would be kept in a room with a pretty constant temperature and snow would would not be allowed to accumulate on the roof.
Please let me know what you think and what equipment you believe I will need.
Dear John,
I think you might detect only one background neutron every few hours so it would be very hard to detect a pattern. The only additional information I would have is that which is on our website regarding the neutron tube.
From another page Page 2 which might help with muon pattern probability:
As mentioned elsewhere, Professor Jim C. Yu has written a lesson using
the RM-60 and software in combination with a spreadsheet wherein
students plot the frequency distribution of background radiation. This
generates the classic bell shaped curve. Also calculated: Mean and
standard deviation. To view gif images of lesson generated
