Background
The gas-filled ionization chamber radiation detector is mainly used for monitoring gamma radiation absorption dose rate in nuclear engineering and nuclear power station containment, and measuring ionization radiation by utilizing ionization effect, wherein the ionization radiation generates ionization ion pairs in a medium, and positive and negative ions drift to a negative electrode and a positive electrode respectively under the action of an electric field to form ionization current.
