Abstract :
Lithium Fluoride (LiF) Thermoluminescent Dosimeters (TLD´s) have been used extensively as a diagnostic in radiographic facilities. For over three years we have used precision-calibrated TLD´s in our facility. Said facility consists of two radiographic sources, each with a dose rating of 4-Rad at 1 m. The calibration and fielding of TLD´s will be examined for accuracy and long term stability. TLD´s will be evaluated in single point measurements and multi-point arrays. Overlaying three-chip TLD measurements will be compared to single chip TLD measurements. TLD results will also be compared to Pin Diodes for routine shot diagnosis and evaluation of shielding around the sources.
