Description: Gamma rays are naturally emitted wavelength from outer space and the earth’s surface. Gamma sensors measure these gamma rays. Water (and snow water equivalent) attenuate gamma rays The theory of operation of a gamma ray sensor system is to place one gamma ray receiver above the snowpack and one at the bottom of the nowpack. The difference in measured gamma rays is proportional to the amount of water in the snow pack. Since gamma rays over a given area are somewhat uniform, the concept of measuring incoming gamma rays from a central location, and then placing receivers under the snow pack in the general vicinity of the gamma incoming receiver is being investigated and modeled. This will make the application of the gamma sensor technology even more affordable and applicable.
Costs USD Lower: $15,000
Costs USD Upper: $20,000
Accessories: ACCESSORIES
Advantages: Not impacted by snow bridging events
Disadvantages: Relatively more expensive than fluid and fluidless snow pillows. Accuracy limitation with increased snow pack.
