摘要:
The invention relates to a thermoluminescence detector and method for production thereof. The aim of the invention is to develop a detector for the direct marking of the detector, permitting a heat-resistant permanent identification of the detector. Said aim is achieved by means of a cover layer made from a silicon resin with finely distributed pigment particles therein. The layer thickness lies between (30) and (50) mu m and a coding is generated by means of an almost quantitative vaporisation of regions of the cover layer with a laser according to selectable patterns.
摘要:
The present invention relates to a method for recording polarized electromagnetic radiation of an inactivated strain of pathogenic microorganisms onto a crystal, a method and a device for changing the activity of a strain of pathogenic microorganisms, a method for eliminating a strain of pathogenic microorganisms in a human or animal organism. The invention may be used for inactivation and stibsequent elimination of pathogenic and conditionally pathogenic microorganisms in a human or animal organism.
摘要:
The invention relates to a filament comprising thermoluminescent particles that are evenly distributed in a polymer matrix, characterized in that the polymer matrix is a thermoplastic polymer having sufficient adhesion with respect to said thermoluminescent particles in order to ensure the cohesion of said filament and being such that the thermoluminescent response (signal) of the filament corresponds substantially to the dose of radiation absorbed and obtained after the filament is placed in contact with a physiological medium. The invention also relates to a method for thermoluminescence-based measurement of doses of beta radiation delivered by a transmitter on a target organ of a mammal, characterized in that a group of inventive filaments is introduced to the desired spot, whereby part of the length of said filaments remains outside the irradiated area, and in that the filaments are removed after irradiation and thermoluminescence is determined.
摘要:
A luminescent glass includes nanocrystalline semiconductor particles, such as ZnS nanocrystals, and an activator, such as copper, for the particles. The glass is made by depositing the nanocrystalline semiconductor particles and the activator within a porous glass matrix, such as 7930 VycorTM and then thermally activating the glass. The porous glass matrix may be at least partially consolidated or may be allowed to remain porous. The nanometer particle size permits the luminescent glasses of the present invention to be transparent to its luminescent emsissions.
摘要:
The amount of ionizing radiation to which a thermoluminescent material has been exposed is determined by first cooling the thermoluminescent material to a cryogenic temperature. The thermoluminescent material is then optically stimulated by exposure to ultraviolet light. Visible light emitted by the thermoluminescent material as it is allowed to warm up to room temperature is detected and counted. The thermoluminescent material may be annealed by exposure to ultraviolet light.

The present invention is a composite material containing a mix of dosimeter material powder and a polymer powder wherein the polymer is transparent to the photon emission of the dosimeter material powder. By mixing dosimeter material powder with polymer powder, less dosimeter material is needed compared to a monolithic dosimeter material chip. Interrogation is done with excitation by visible light.
摘要:
The amount of ionizing radiation to which a thermoluminescent material (40) has been exposed is determined by first cooling (70) the thermoluminescent material and then optically stimulating the thermoluminescent material and then optically stimulating the thermoluminescent material by exposure (72) to light. Visible light emitted by the thermoluminescent material as it is allowed to warm up to room temperature is detected and counted (74). The thermoluminescent material may be annealed (76) by exposure to ultraviolet light.
