Thermoluminescent dosimetry using lithium fluoride in aqueous suspension

The suspension of solid TLD microcrystals in a liquid medium offers considerable advantages in radiation dosimetry. This paper describes the characteristics of an aqueous suspension of a thermoluminescent grade of LiF. Although the thermoluminescent parameters of a given phosphor are changed after contact with water and the subsequent preparation procedures, the system may be used in practice, and a method for its routine use is described.
