Abstract

The use of Lithium Fluoride (LiF) Thermoluminescent Dosimeters (TLD) have been in use at a radiographic facility for over three years. The facility consists of two radiographic sources each with a dose rating of ~4-rad at 1 m. The calibration and fielding of LiF TLD´s will be examined for accuracy and long term standard deviation of these measurements. LiF TLD´s will be evaluated in single point measurements and multi-point arrays. Improved multi-point arrays will be compared to previous array data. The LiF TLD´s will also be compared to Pin Diodes for routine measurements and evaluation of shielding around the sources.
