[en] A patent application has been made for an ionization dosimeter containing an ionization chamber, an integrating amplifier and a power supply. The purpose of the invention is to improve the accuracy of continuous dose measurement. The distinctive features of the dosimeter is that it contains a threshold device, a trigger with two switches and a voltage divider on four resistors. The power supply is ungrounded and connected to the potential terminals of the threshold device and to the end terminals of the voltage divider. The middle terminal of the voltage divider is connected with the potential terminal of the ionization chamber and the two intermediate ones are connected across the trigger-controlled switches to a grounded bus-bar.
