摘要： A shock, detonation, and damage location sensor providing continuous fiber-optic means of measuring shock speed and damage location, and could be designed through proper cabling to have virtually any desired crush pressure. The sensor has one or a plurality of parallel multimode optical fibers, or a singlemode fiber core, surrounded by an elongated cladding, doped along their entire length with impurities to fluoresce in response to light at a different wavelength entering one end of the fiber(s). The length of a fiber would be continuously shorted as it is progressively destroyed by a shock wave traveling parallel to its axis. The resulting backscattered and shifted light would eventually enter a detector and be converted into a proportional electrical signals which would be evaluated to determine shock velocity and damage location. The corresponding reduction in output, because of the shortening of the optical fibers, is used as it is received to determine the velocity and position of the shock front as a function of time. As a damage location sensor the sensor fiber cracks along with the structure to which it is mounted. The size of the resulting drop in detector output is indicative of the location of the crack.

摘要： Disclosed is a laser dosimeter reading apparatus having a controllable optical laser converter for providing multiple stimulating laser beams. The converter laser dosimeter reader can be used to stimulate or otherwise treat dosimeter elements to perform two or more distinct processes on a particular dosimeter element. Additionally, the convertible dosimeter reader can be used to read multiple different types of dosimeter elements contained on a single dosimeter badge, thereby allowing a badge to be read in a multi-stage reading operation in a single dosimeter reader which is preferably automated. The optical laser converter includes a converter block assembly which defines multiple optical pathways therethrough. The convert block assembly is movable between different positions to align the different optical pathways with an incoming laser beam. The output laser beams from the different optical pathways of the converter have differing laser beam characteristics suitable for different types of dosimeters or differing treatment processes. The output beams from the optical pathways are preferably passed through an imaging assembly which images the beams onto the dosimeters being stimulated or for other uses as the laser beam converter may be utilized. The disclosure also includes methods for converting a laser beam and for reading radiation dosimeters.

摘要： A thermoluminescent radiation detector crystal which has been irradiated by ionizing radiation is contacted with an organic solvent at its boiling point prior to read-out of the crystal. The boiling point of the solvent is approximately equal to the optimum post-radiation annealing temperature of the crystal. The solvent thereby simultaneously cleans and anneals the crystal. Preferably, the contacting step is performed by suspending the crystal in vapors of the solvent. The vapor condenses on the crystal and washes away impurities from the surface thereof.

摘要： A standard light source utilizing spontaneous radiation made by mixing a fluorescent substance LnVO4:X (wherein Ln is Y or Gd, and X is Dy or Eu) with a radioactive substance containing a radioactive isotope which is less in the degree of temperature variation of the intensity of emitted light and excellent in stability.
