WebSingle element dosimeters and assemblies are widely used in many installations and processed using Harshaw TLD Systems. These systems include a range of readers and irradiators with compatible software to implement calibration, radiation evaluation and management, dose algorithms, health physics record keeping, finder database, glow … WebThe variation in the light output with temperature is called a glow curve. There are certain temperature peaks where the light output is greater. These peaks will vary with the type of TLD material. The TLD processing equipment is programmed to detect and record the light output corresponding to these peaks (Figure 12.8C). The magnitude of the ...
