				Background Neutron Count at Different Altitudes                              recorded near                    Calgary, Alberta, Canada
		The following observations were all taken in the vicinity of Calgary, Alberta, Canada. All were taken within a three hour period, starting at 3:45 PM on Sunday, July 30, 2006. The altitudes were derived from a handheld GPS, and the highest and lowest altitudes were verified with topographical maps. The neutron readings were taken with a Reuter Stokes RS-P4-0820-103 Helium 3 detector tube and a Ludlum model 2000 scaler, using a voltage of 1700 volts. No moderator was used with the tube. Note that since this equipment has not been calibrated, the absolute values are meaningless. However a valid comparison can be made of the relative magnitude of the counts recorded. (Calibration would allow us to convert the readings obtained to the actual number of neutrons per cm. per minute. It would take into account the size of the active area of the tube and the tube's efficiency.)
