natural gamma ray spectroscopy Energy Glossary

WebThe technique of measurement of natural radiation in the earth’s surface is called “radiometric method” (also known as Gamma ray spectrometry). This is a process in which the unstable atom becomes stable in the process of its nucleus. Energy is released in the form of radiation, viz., alpha, beta, and gamma rays.
