Remote Sensing of Snow Covers Using the Gamma-Ray Technique

Abstract : This report reviews various aspects of the use of natural gamma-ray emissions to determine the mass of snow covering the ground. The interactions of gamma rays with water mass are described, along with the various sources of gamma radiation from the ground. Different possible techniques for measuring gamma radiation are described. Each has advantages and disadvantages in obtaining the desired result. The sources of error and the use of this method are described.
