METHOD OF PREPARING DOPED LITHIUM FLUORIDE THERMOLUMINESCENT RADIATION DETECTOR

摘要

A process for preparing doped lithium fluoride suitable for use as a thermoluminescent radiation-sensitive material comprises the sequential steps of: 1) preparing a mixture of microcrystals of lithium fluoride and one or more dopants; 2) heating the mixture at a temperature at which the dopants can diffuse into said microcrystals for a period of time sufficient to produce sensitized microcrystals of lithium fluoride; 3) hot pressing the sensitized lithium fluoride microcrystals for a period of time sufficient to prepare a compact of doped polycrystalline lithium fluoride; 4) cooling the compact to room temperature.
