Abstract: A personnel dosimetry method and system wherein the identity of a radiation field mixture is determined by using the correlation between two ratios of the responses of two pairs of three TL elements that are filtered to respond differently to the mixed radiation field. Also described is a calibration methodology which links the response of a dosimeter to a variety of different radiation fields calibrated by a standardization agency to the response of the dosimeter to a local and uncalibrated reference source by definition of a local reference of generic unit.

Abstract: A method of preparing colloidal sols of pentavalent antimony containing increased amounts of metal is described. More particularly, a method of converting substantially water-insoluble metal antimonates to colloidal sols of pentavalent antimony is described. The method comprises mixing a substantially water-insoluble metal antimonate with a pentavalent antimony sol and agitating the mixture for a period of time sufficient to convert at least a portion of the crystalline metal antimonate to the colloidal state. The colloidal sols obtained in the described manner contain an increased amount of the metal, and such sols are useful as flame-retardants.

Abstract: The addition of a getter consisting essentially of reactive oxides of boron and silicon, to a melt of an alkali metal halide serves to overcome problems of unacceptable color, afterglow and hardness attributable to trace impurities present in the melt. These trace impurities are generally metals present in a concentration less than 1 part per million (ppm) parts of melt. An ingot melt-grown from charge stock treated with the getter provides high quality optical bodies such as light pipes, laser windows and scintillators. Specific problems characteristic of a scintillator ingot grown from a highly purified alkali metal halide "remelt", such as is obtained by crushing and melting portions of a melt-grown ingot, are overcome by adding to the remelt a portion of fresh powder stock in which the getter has been uniformly distributed.A process is taught for the Stockbarger growth of a scintillator ingot from a charge stock treated to include a getter consisting essentially of the combined reactive oxides of boron and silicon, comprising superheating a melt of treated charge stock for a period of time sufficient to react at least some of the reactive oxides with deleterious trace impurities present in the melt, and growing a scintillator ingot free from discoloration, afterglow or undue hardness due to the presence of the impurities.

Abstract: A polycrystalline shaped article useful as a light-transmitting body or scintillation phosphor is formed from an essentially moncrystalline melt-grown macrocrystal ingot by pressing the ingot between opposed surfaces with no radial restraint, at a temperature below its melting point and under sufficient pressure to transform the ingot, in situ, into a fully dense, homogeneous, polycrystalline mass of unrestricted width.A polycrystalline shaped article useful as a light-transmitting and/or light-generating body may also be formed from a fully dense, homogeneous, optically integral polycrystalline mass by pressing the polycrystalline mass between opposed surfaces with no radial constraint, at a temperature below its melting point, but greater than one-half its melting point measured in degrees centigrade, under sufficient pressure to form a relatively larger polycrystalline mass of lesser height.

Abstract: A method for extracting antimony from solids containing antimony sulfides is described. An improvement in the method of extracting antimony by oxidation of an aqueous mixture of the solids in an acid or by oxidation of a leaching liquor obtained by leaching the antimony from the solids with an aqueous basic solution comprises conducting the oxidation in the presence of a catalyst comprising a water-soluble copper salt, a quinone, a hydroquinone or mixtures of one or more of these. The catalyst significantly increases the rate of oxidation and the rate of the recovery of the antimony from antimony sulfide bearing solids, particularly natural ores. Where the oxidation is conducted in a basic solution, the antimony is recovered as pentavalent antimony in the form of metal antimonates. Facile reduction of the metal antimonate to antimony trioxide also is described.
