Abstract: A combination portable ionization chamber and support for mounting and adjustably aligning the chamber to an X-ray cassette so that the ionization chamber is accurately positioned in line with a source of radiation and a body part or object being X-rayed wherein the support is suspended from the X-ray cassette and retains the ionization chamber in position abutting the rear surface of the X-ray cassette so that when sufficient radiation has been detected by the ionization chamber to insure an acceptable radiograph, power to the radiation source will be automatically terminated.
