Ionizing chamber

Web21 mrt. 2024 · ionization chambers are dosimetry devices used to measure the output of x-ray tubes. They function as photo timers in automatic exposure controls and in nuclear medicine, as dose calibrators. pocket ionization chambers are a portable form of dosimetry devices in the shape of large pens. WebThis voltage is higher than that used in ionization chamber detectors (e.g., Fluke 451B). Because of this, the GM counter is less accurate, but more sensitive. When ionizing radiation passes through the gas chamber, it causes gas molecules to ionize and travel toward the charged electrodes, sending a pulse of current.
