    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.

    Abstract: For simultaneously measuring the radioactivity of multiple samples arranged in a predetermined array of x rows and y columns, a fixed array of radiation counters arranged in the same array of x rows and y columns so that one of the counters is aligned with each of the multiple samples. Each of the counters has a pair of spaced electrodes; an electrical voltage source connected to the electrodes of all the counters for applying the same voltage across the electrodes of each of the radiation counters in the array; and sensing means connected to the electrodes of each of the radiation counters for independently detecting pulses of electrical current produced by ionization of the gas between the respective pairs of electrodes of each of the radiation counters. For measuring low-energy radiation, the radiation counters are windowless, a flow of ionizable gas is supplied to the counters, and the same flow rate of the ionizable gas is maintained through each of the radiation counters in the array. Preferably the radiation counters are formed in a metal plate that provides shielding to minimize "cross talk" between adjacent samples.

    Abstract: A wide range radiation dose rate meter for civil defense use, including a iger-Mueller tube used in a continuous counting mode and for measuring dose rates from the natural background to about 30. rads/hr., with an ion chamber arranged to measure higher dose rates up to 10,000 rads/hr. The instrument has a sample and record capability in which the selected radiation detector will have its output connected to a selected storage capacitor for a precise interval of time determined by a timing circuit and the storage capacitor will accumulate and hold a voltage proportional to the dose rate, which can be read by means of an electrometer at a later time. The instrument has a self contained hand cranked power supply and all components are selected for long shelf life.

    Abstract: A highly sensitive Geiger-Mueller radiation detector with improved temperature stability and working life uses a cylindrical cathode made from a nickel copper alloy preferably containing predominantly nickel. This alloy is resistant to attack by halogen quench gases used in the tube and provides an excellent surface for the electrodeposition of platinum to provide a low porosity surface.

    Abstract: A radiation-detecting device which is mounted on a gas-turbine engine to receive radiations from the afterburner combustion-zone, includes a gas-filled electrical discharge tube that is located within a tubular nose of the device and is pulse energized. The ultra-violet component of radiations from the zone and distinctive of the presence of flame in the afterburner, is transmitted to the discharge tube via a sapphire plano-convex lens, the infra-red component being attenuated by a thin gold-film coating on the planar face of the lens, whereby discharge takes place in the tube with each energizing pulse only while the flame is present. The sensitivity of the detecting device to ultra-violet radiation is enhanced by internal reflections from reflective coatings on the inner surface of the tubular nose and the glass envelope of the discharge tube. The count of a counter is advanced stepwise with each pulsing of the discharge tube towards a maximum count of 8 (or 16), and is reset to zero in response to each tube discharge so that the counter overflows only after the tube remains quiescent through more than 8 (or 16) consecutive pulsings. Overflow of the counter signifies positively the flame-out condition and initiates warning and relighting action by a control unit.

    Abstract: A bromine doped self-quenching Geiger-Mueller tube having an operational life expectancy in excess of 1,200 hours at a temperature of 315*C. The tube comprises a passivated metal coated cathode which is conditioned or aged for operation at room temperature, thus obviating the necessity of thermally cycling the tube at progressively elevated temperatures. Useful metal coatings for the cathode include chromium, platinum, and nickelcopper alloys deposited in a layer less than about 1 mil thick. A method for passivating the metal coated cathode and subsequently conditioning the tube and its contents is disclosed.
