Disk type thermoluminescent detectors by sintering LiF phosphor activated with Mg Cu Na and Si and its manufacturing method

摘要

The invention LiF in Mg, Cu, Na, and Si is the LiF is added as impurities: Mg, Cu, Na, Si column phosphor powder (the LiF: Mg, Cu, Na, Si) a disk-like made by sintering (sintering) It relates to a radiation detection element. An object of the present invention is a powder form of LiF: Mg, Cu, Na, by developing the solidified elements to reproduce the unique characteristics for the radiation in the Si heat phosphor has, each element are disk-shaped, which serves for independent detection elements to provide a radiation detection device and a method of manufacturing the same. These detection devices are easy to handle than the powders, and may be variously used for radiation detection, in particular used as the components that make up the individual exposure dosimeter badge.; The invention LiF: put the device of the Mg, Cu, Na,; and pressing the formed disc-like molding of about 10 ± 3 ton disc-shaped by applying pressure in a press at room temperature, Si powder in an electric furnace 820 ± 10 ℃ through the step of heat treatment of about 60 ± 30 minutes at temperature, LiF powdered: Mg, to a method of preparing a disk-like radiation detection element according to reproduction of the unique characteristics of the Cu, Na, radiation in the Si material has.
