Flexilicate manufactures thermos-luminescent dosimeter (TLD) using glass optical fibers for various applications. The fiber dosimeters are fully compatible with standard TLD readers without requiring any modification.
The main advantages of fiber TLDs are very high spatial resolution, impervious to water and humidity, easy handling, and lower cost.
