Ionization Chamber Instrumentation
2021
Ionization chambers are an essential device for measurement of radiation dosimetry and have been used for a long time. Chambers have various shapes but the most general type is a cylindrical chamber. The measurement process depends on the ionization process and the high voltage to collect the charge. The basic components of the chamber determine the response of the chamber. Each of the characteristics of ionization chambers is reviewed and explained. Electrometers and cables are essential for the complete system. Cables are the major source of leakage and should be well cared for. Corrections for the density of the gas in the chamber must be done. In addition, recombination and polarity effects are generally the other major corrections needed.
