Cooled Optically Stimulated Luminescence uses light at or below room temperature to obtain radiation dose information.
1995 - Cooled, Optically Stimulated Luminescence (COSL)
Developer: Steven D. Miller
This technology measures radiation in dosimeters and other thermoluminescent materials. In the COSL process, a dosimeter is cooled to the temperature of liquid nitrogen and then exposed to ultraviolet light. As the dosimeter warms, it gives off visible light similar to thermoluminescent dosimeters. Dosimeters can be re-read and a variety of packaging is greater because no heat is involved.
