Gamma Spectrometer Block Diagram:

Gamma spectroscopy is a radiochemistry measurement method which determines the energy and count rate of gamma rays emitted through radioactive substances. It is a very important measurement. A complete analysis of the gamma ray energy spectrum is used to determine the identity and quantity of gamma emitters present within a material.

The equipment used in gamma spectroscopy involves a detector, a pulse sorter (multichannel analyzer), and related amplifiers and data readout devices. The detector is generally a sodium iodide (NaI) scintillation counter.  Below figure displays a block diagram of a gamma spectrometer.
