摘要:
An optically stimulated luminescence (OSL) dosimeter system. An OSL reader configured to produce data indicative of a radiation exposure, one or more OSL dosimeters fabricated from a thermoluminescent material, a light stimulation source configured to stimulate the OSL dosimeter to produce luminescence emissions, and a light-detection system that measures the intensity of such luminescence emissions and converts the electrical signal to a binary string that can be processed by an appropriately programmed computer configured to analyze data from the reader and produce data indicative of an extent of radiation exposure. Dose information is obtained without requiring heating of the dosimeter. The dosimeter can be interrogated multiple times with minimal loss of dose information.
