Method of thermoluminescence dosimetry (TLD) is based on the ability of some materials to store energy ionizing radiation to which they are exposed. The stored energy can be stored for a long time and released in the form of heat radiation during heating of these substances.
Single 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 curve analysis and chain of custody monitoring.
