Quick Summary

In radiation measurement, the "pulse mode" is used to generate a distinct electrical pulse for each individual quantum of radiation detected. This pulse's amplitude is directly proportional to the amount of charge (Q) liberated by the radiation within the detector material. The amplitude (V_max) is calculated as Q/C, where C is the capacitance of the measuring circuit.1

Spectroscopy systems utilize this pulse amplitude to sort and analyze radiation. By measuring the distribution of pulse amplitudes, scientists can determine the energy distribution of the incident radiation. Peaks in a pulse-height spectrum indicate radiation of specific energies. Amplitude, in physics, refers to the maximum displacement from an equilibrium position, such as in a vibrating body or wave.23
