    Abstract: A dosimeter is described that does not show differences in sensitivity over its sensitive area when the ambient pressure changes. To that purpose the measuring chamber and a pressure compensation element together form a single gas tight chamber having at least partially of slack material, wherein the pressure inside the measuring chamber is essentially equal to ambient pressure such that no mechanical distortion of the measuring chamber over its sensitive area takes place.

    Abstract: Improved binary and tertiary gas mixtures for gas-filled particle detectors are provided. The components are chosen on the basis of the principle that the first component is one gas or mixture of two gases having a large electron scattering cross section at energies of about 0.5 eV and higher, and the second component is a gas (Ar) having a very small cross section at and below aout 0.5 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 electron 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: A Geiger-Mueller tube includes a tubular, stainless steel cathode (A) which defines a chamber (B) therein. An anode (C) extends axially through the chamber in a spaced relationship with the cathode. A thin layer of rhenium (20) is plated on an interior surface (12) of the cathode. End caps (32, 36) and ceramic fittings (34, 38) hermetically seal the ends of the cathode tube. The cathode chamber is charged with a gaseous mixture including in primary part noble gases, such as neon and argon, and about 1-3% bromine or other halogen gases. The Geiger-Mueller tube with a rhenium plated cathode is relatively inexpensive to manufacture, provides excellent bromine and halogen degradation resistance at elevated temperatures, and provides superior, linear operating characteristics over a wide range of temperatures.
