Patent ID: 7592609

Claim:
A method for fabricating a thermoluminescent dosimeter for radiation monitoring, wherein the thermoluminescent dosimeter comprises LiF doped with Mg, Cu and Si, and the method comprises the steps of: (A) heating a LiF-based thermoluminescent powder material containing a LiF mother material, 0.1-0.5 mol % of an Mg compound, 0.001-0.05 mol % of a Cu compound and 0.5-1.3 mol % of an Si compound to a temperature of 900-1200° C. to melt the LiF-based material; (B) cooling the melted material obtained in the step (A) and compression-molding the cooled material; (C) sintering the compression-molded material at a temperature of 760-840° C. in an inert gas atmosphere; (D) subjecting the sintered material to a first-step annealing process at a temperature of 285-305° C., followed by cooling; and (E) subjecting the annealed material obtained in the step (D) to a second-step annealing process at a temperature of 255-265° C., followed by cooling.
