Introduction
The POTENTIAL of thermoluminescent radiation dosimetry has been recognized in recent years, and several materials are now in use as thermoluminescent dosimeters. The thermoluminescent material which is most widely used at the present time is lithium fluoride. We have investigated some of the thermoluminescent properties of ruby (A12O3:Cr3+), (0-05%) sapphire (A1203), and lithium fluoride (TLD-100). Initial results indicate that ruby possesses several characteristics which compare very favorably with the thermoluminescent materials now available. Several authors have reported some studies on the thermoluminescence of ruby and sapphire in regard to color center phenomena.
