Ionization Chamber

An ionization chamber (or ion chamber) is often portable. An ion chamber is used to measure the rate of radiation exposure (how much radiation exposure is being received in a specified period of time). The ability of the ion chamber to measure the exposure rate from a radionuclide is based upon the ability of the emission to reach the active portion of the meter and the energy of the emission. Ion chambers are used where there is measurable exposure to or potential for measurable exposure to x and gamma rays.
