Background

The ionization chamber is a detector, also called an ion chamber, that measures ionizing radiation by utilizing the ionization effect of the ionizing radiation. The ionization chamber is composed of electrodes at different potentials and a medium therebetween. The ionizing radiation generates ionized ion pairs in the medium, and under the action of an electric field, positive and negative ions drift to the negative electrode and the positive electrode respectively to form ionization current. Since the ionization current is proportional to the intensity of the radiation, measuring this current yields the intensity of the ionizing radiation.
