摘要： An electrostatic alpha radiation detector for measuring alpha radiation emitted from inside an enclosure (11) comprising an electrically conductive expandable electrode (ECEE) (13) for insertion into the enclosure. After insertion, the ECEE is insulated from the enclosure and defines a decay cavity (11a) between the ECEE and the enclosure so that air ions (14) generated in the decay cavity are electrostatically captured by the ECEE and the enclosure when an electric potential is applied between the ECEE and the enclosure.

摘要： An alpha detector (10) for application in areas of high velocity gas flows, such as smokestacks and air vents. An odd-numbered plurality of spaced apart signal collectors (13) are placed inside an enclosure, which would include smokestacks and air vents, in sufficient numbers to substantially span said enclosure so that gas ions generated within the gas flow are electrostatically captured by the signal collector means. Electrometer means (17) and a voltage source (16) are connected to the signal collectors to generate an electrical field between adjacent signal collectors, and to indicate a current produced through collection of the gas ions by the signal collectors.

摘要： Information on radiation dosage from segmented ionization chambers (10) can be incomplete due to the existence of insensitive regions of the chamber. By measuring the total current to the high voltage power supply (16), the total ionization current including that in the insensitive areas can be estimated, thereby providing a measure of the dosage to the insensitive areas.

摘要： A portable device for measurement of radiation having at least two Geiger-Muller counter tubes (42 and 44) of different sensitivity. A high-voltage supply (48) is in connection with each Geiger-Muller tube and pulse shaping devices (60 and 62) are connected to the Geiger-Muller tubes to generate output signals based on the intensity of radiation. A high-speed counter (64) is coupled to the pulse shaping devices. A microprocessor (46) includes program storage and random access memory and is capable of switching between the Geiger-Muller tubes based on the radiation intensity. Information generated by the high-speed counter and the microprocessor is visually displayed. Stable and accurate readings are made at low radiation intensity while providing quick response to significant changes in radiation intensity.

摘要： The object of the invention is a device for measuring of ionizing radiation, to which device belong a high voltage source (1), a radiation detector (2), favourably a Geiger-Muller tube, in which the radiation quantum together with the voltage generates an ionic current and the radiation detector becomes conductive, detecting instruments (9) for indication of the ionic current, and a with the cathode side of the radiation detector connected voltage source (4), which is arranged to conduct to the radiation detector a counter voltage, which quenches the ionic current. The present devices are complicated and it is not possible to measure with the help of them a continuously ionizing radiation. In a device in accordance with the invention the voltage source and the radiation detector are connected with the earth with one coupling (6) and to the device belongs a with the coupling and with the detecting instruments of the ionic current connected controlling apparatus (8), which is arranged to open the coupling, when a radiation quantum hits the radiation detector, whereat the voltage is conducted to the cathode of the radiation detector to act as a quenching voltage.

摘要： An inner cylindrical cathode (112) and outer cylindrical cathode (106C) are concentrically positioned about a vertical center axis. Vertical anode electrodes (130) extend parallel to the center axis and are symmetrically arranged around the inter-cylinder space (126I) between the cathodes. The ends of the anode wires are supported by a pair of insulator rings (132T) and (132B) mounted near the top and bottom of the cathode cylinders. A collection voltage applied to each anode wire (130) for establishing an inward radial E field to the inner cathode cylinder (112) and an outward radial E field to the outer cathode cylinder (106). The anode-cathode assembly is mounted within a housing (106) containing a conversion gas. A radioactive sample (116) is inserted into the inner cathode (112) which functions as a tubular, deep well radiation window between the sample environment and the conversion gas environment. A portion of the gamma radiations passing through the inter-cylinder region (126I) interact with the conversion gas to produce free electrons which are accelerated by the E fields and collected on the anode wires (130). The extremely small diameter of the anode wires intensifies the electric fields proximate each wire causing avalanche multiplication of the free electrons resulting in a detectable charge pulse.
