Abstract: Improved binary and ternary gas mixtures for gas-filled radiation detectors are provided. The components are chosen on the basis of the principle that the first component is one molecular gas or mixture of two molecular gases having a large electron scattering cross section at energies of about 0.5 eV and higher, and the second component is a noble gas having a very small cross section at and below about 1.0 eV, whereby fast electrons in the gaseous mixture are slowed into the energy range of about 0.5 eV where the cross section for the mixture is small and hence the electron mean free path is large. The reduction in both the cross section and the electron energy results in an increase in the drift velocity of the electrons in the gas mixtures over that for the separate components for a range of E/P (pressure-reduced electric field) values. Several gas mixtures are provided that provide faster response in gas-filled detectors for convenient E/P ranges as compared with conventional gas mixtures.

Abstract: A direct ion storage (DIS) radiation detector or dosimeter has a design that is easy and low cost to manufacture using semiconductor processing techniques. The detectors include internal communications interfaces so they are easy to read. Different interfaces, including wired, e.g. USB ports, and wireless interfaces, may be used, so that the dosimeters may be read over the internet. The detectors can thus be deployed or used in a variety of detection systems and screening methods, including periodic or single time screening of people, objects, or containers at a location by means of affixed dosimeters; screening of objects, containers or people at a series of locations by means of affixed dosimeters, and surveillance of an area by monitoring moving dosimeters affixed to people or vehicles.

Abstract: Le dosimètre décrit se caractérise par le fait qu'il ne présente pas de différences de sensibilité sur sa surface sensible lorsque la pression ambiante change. A cet effet, la chambre de mesure et un élément de compensation de pression forment ensemble une chambre étanche au gaz unique constituée au moins partiellement de parois en matériau mou. Ainsi, la pression régnant à l'intérieur de la chambre de mesure est sensiblement égale à la pression ambiante, de sorte qu'aucune distorsion mécanique de la chambre de mesure sur sa surface sensible ne se produit.

Abstract: To enable an ionisation chamber used for measuring the intensity of a beam of ionising radiation, for example an electron beam produced by a linear accelerator and used for radiotherapy, both to give an output signal which is independent of ambient pressure and temperature and to present a low weight of scattering material per unit area to the beam, the chamber is of flexible construction so that the volume of gas in it adapts to ambient pressure and temperature and such that the weight of gas in the active region between the electrodes per unit area remains substantially constant. Suitably, the electrodes are conductive layers on flexible plastics sheets (1, 2), an outer annular portion (6) of one sheet (2) providing a flexible connection between two opposed chamber wall portions which remain substantially planar and parallel; the proportional change (ΔV 1 /V 1 ,) in a volume bounded by the opposed wall portions and including the active region equals the proportional change (ΔV 2 /V 2 ) in the remainder (V 2 ) of the internal volume.

Abstract: PURPOSE:To obtain a radiant ray detecting device which can save remarkably a gas consumption by disposing a counting gas refiner for eliminating an impure component in counting gas, on the counting gas leading-in side of a gas flow counter. CONSTITUTION:The counting gas supplied to the gas flow counter train consisting of (m) pieces of cascaded gas flow counters 51, 52... 5m, through an opening and closing valve 2, a pressure regulator 3 and a flow meter 4 from a counting gas cylinder 1 is discharged into the air through a check valve 6. In this case, the counting gas refiners 71, 72...7m are inserted and disposed at the gas inflow side of each gas flow counter respectively. When Q gas is used as the counting gas, it obtains a prescribed characteristic of the gas flow counter, therefore, water in the Q gas which is transmitted a radiant ray incident window 21 is eliminated from the Q gas by the characteristic difference of a boiling point, etc., the transmission of the water by a semipermeable member or a gas refiner utilizing an adsorption, etc. In this way, it becomes unnecessary to flow more gas quantity than the gas quantity operating effectively for counting a radiant ray, in order to reduce the impure component density in the counting gas, and the counting gas can be saved remarkably.

Abstract: PURPOSE:To obtain a specific gas amplifier by forming at least a portion of an enclosed housing provided with an incident window for radiation with movable wall face for varying the inner capacity while adjusting the gas density easily after manufacture. CONSTITUTION:For example, a tubular auxiliary chamber 7 is provided at a portion of housing 1 to fasten a screw 8 onto the bottom face while a bellows 9 is contained to bond one end to the bottom face of housing 1 thereafter the bellows 9 and housing 1 are communicated through a hole 10 to bond the leading edge of the screw 8 rotatably to the bottom plate 11 fixed to the other end of bellows 9. Upon rotation of screw 8, the bellows 9 is expanded or compressed to vary the inner capacity of housing 1 thus to set the density of electrolytic dissociation gas at desired level.
