ABSTRACT:
A process for preparing doped lithium fluoride suitable for use as a thermoluminescent radiation-sensitive material includes 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.
