Gamma Ray Spectroscopy is a technique used to analyze the energy and intensity of gamma rays emitted by radioactive materials. By measuring these gamma rays, scientists can identify the isotopes present in a sample and determine their concentrations. This method is widely used in fields such as nuclear physics, environmental monitoring, and medical diagnostics. The process involves using a detector, often a semiconductor or scintillation detector, to capture gamma rays. The detected signals are then processed to create a spectrum, which displays the energy levels of the gamma rays. This information helps researchers understand the composition and behavior of various materials.
