IPC: G01T1/115
Filed: 1968-06-28
Abstract: 1,259,836. Uses of luminescence. UNITED KINGDOM ATOMIC ENERGY AUTHORITY. 27 June, 1969 [28 June, 1968], No. 31160/68. Heading C4S. [Also in Division G1] A thermoluminescent dosimeter is retained in a holder bearing indicia associated with the dose being measured, e.g. identifying the user, to enable the indicia and the dose to be read out without the dosimeter being removed from its holder. The dosimeter holder of Fig. 1A has a pattern of holes 4 punched in a unique combination to indicate in binary code user information. Alternatively magnetic ink, stored electrical or magnetic signals, could be used. A further alternative would be indicia in a form allowing pneumatic readout. The dosimeter holder of Fig. 1A also carries two dosimeter discs 2, 3, one of which is covered during exposure. The device is read out using, for example, the apparatus of Figs. 2, 3 and 4 (not shown) (see Division G1). The dosimeter holder is inserted in a shaped recess in a slide, which is first moved to a first position between an array of light sources and a corresponding array of photodiodes, where the user indicia are read out. The slide is moved further to locate the first dosimeter disc over an electrical heating element, so that the disc is also located directly beneath a photomultiplier. The heater is raised and energized. Either the light emitted by the disc may be integrated (by a sealer) between two temperature limits, and the dose calculated therefrom printed out next to the user information, or the detector output is measured continuously and a continuous record of intensity and temperature recorded on a 2- channel chart recorder, from which a gloss curve may be plotted. The slide is then moved on to bring the second disc into the readout position and thus is read. A modified slide, with a hinged lid for the holder recess, is described Figs. 5-7 (not shown). An alternative apparatus for reading indicia in the form of punched holes, comprises a cam-operated arrangement of contact pins some of which are urged through the holes in the dosimeter holder to electrically contact a block, the pattern of contact areas being recorded.
