Random House Webster's College Dictionary
an apparatus for detecting and analyzing ionizing radiation by measuring current between electrodes in a vessel filled with a gas at normal or lower than normal pressure.
Origin of ionization chamber:
ionization chamber, ionization tube(noun)
a measuring instrument that measures the amount of ionizing radiation
The ionization chamber is the simplest of all gas-filled radiation detectors, and is widely used for the detection and measurement of certain types of ionizing radiation; X-rays, gamma rays and beta particles. Conventionally, the term "ionization chamber" is used exclusively to describe those detectors which collect all the charges created by direct ionisation within the gas through the application of an electric field. It only uses the discrete charges created by each interaction between the incident radiation and the gas, and does not involve the gas multiplication mechanisms used by other radiation instruments, such as the Geiger-Muller counter or the proportional counter. Ion chambers have a good uniform response to radiation over a wide range of energies and are the preferred means of measuring high levels of gamma radiation. They are widely used in the nuclear power industry, research labs, radiography and other medical radiation fields, and in environmental monitoring.
