Abstract:
A substantially stable, substantially portable open-window gas flow Geiger-Mueller type detector capable of monitoring ionizing radiation having an electrically conductive chamber with one or more fluid inlets and opening to receive radiation. A counting gas is provided to the chamber through the inlet(s). The detector also has at least one insulated anode positioned in the chamber and a radiation permeable cover substantially sealed over the opening. A source of electricity is connected to the chamber and electric pulses generated within the chamber are detected when an ionizing event is caused by ionizing radiation entering the chamber.
