The radiation shielding composition and method of the present invention relate to a conformal coating material composed of a matrix of densely packed radiation shielding particles, which are disbursed within a binder. The shielding composition is applied to objects to be protected such as integrated circuits, or to packages therefor, as well as for protecting animals including humans from unwanted exposure to radiation in outer space or other environments.

A detection array for ionizing radiation tomography for obtaining the image of at least one section of an object or organ. The array has at least one chamber (1) provided with a radiation-transparent entrance window (2) and in the chamber a detection stack (E1) incorporating a conductive polarizing plate (3) parallel to the sectional plane and a series of identical electrodes (5) parallel to the sectional plane. An insulating spacer (9) is placed between the electrodes (2) and the plate (5) and ...

An ionizing radiation detector employs optical fibers as the medium for sensing ionizing radiation emitted by a radioactive source. Light in the infrared region is pumped continuously through an optical fiber located in an area or region where the unintentional discharge of ionizing radiation may be expected, so that such emission is detected the moment it occurs. The source of optical light emits a constant output within a specific wavelength band which changes only when irradiation of the fibe...

A method is disclosed treating a tumor in a host by administering an ultrapurified polymerized hemoglobin solution to the host and thereafter administering ionizing radiation, such as X-rays, to the tumor. In a particularly preferred embodiment, the hemoglobin is bovine hemoglobin.

When an ionization section is taken out of a main body housing of a conventional air cleaner in order to wash the ionization section, an ionization line may be cut by being accidentally touched. In order to avoid this problem, a pre-filter (7) is mounted on a front surface of an ionization and dust collection unit (6) so as to be detachable. The pre-filter (7) is slidably guided by guide furrings (23) in a sub-frame (12), and is mounted on a front surface of the sub-frame (12). When the pre-filt...

A field ionizing element formed of a membrane that houses electrodes therein that are located closer to one another than the mean free path of the gas being ionized. The membrane includes a supporting portion, and a non supporting portion where the ions are formed. The membrane may be used as the front end for a number of different applications including a mass spectrometer, a thruster, an ion mobility element, or an electrochemical device such as a fuel cell.

A process for the production of coatings in which the component serving as binder contains olefinically unsaturated polymeric substances having per molecule at least two units of the general formula ##SPC1## Where R, R.sup.1, R.sup.2, R.sup.3 and R.sup.4 are identical or different and denote hydrogen or alkyl of one to four carbon atoms, and the coating is applied to a substrate and cured with ionizing radiation.

In this device a point (100) is brought to a high tension potential by a generator (300). The grounding in case of lightning is effected by a rod (210) brought to the potential of the earth. A spark-gap device is constituted by the base (120) of the point and a crown (240) connected to the rod (210). According to the invention, to protect the dielectric interval of this spark gap, the base of the point is extended downwardly by a flared skirt (130) that covers the crown (240), at least partially...

A housing structure, made of metal, includes at least three interlocking parts, having interengaging elements which operate in different directions, in space, for example elements 1 and 2 being connectable by rotation in one direction, elements 2 and 3 being connectable by vertical movement and, if desired, rotation in another direction to permit ready disassembly of selected elements for cleaning and maintenance without, however, accidental dislodgment of the elements of the structure in case o...

An improved system of circuitry for use in combination with an ionizing-radiation detector over a wide range of radiation levels includes a current-to-frequency converter together with a digital data processor for respectively producing and measuring a pulse repetition frequency which is proportional to the output current of the ionizing-radiation detector, a dc-to-dc converter for providing closely regulated operating voltages from a rechargeable battery and a bias supply for providing high vol...
