Evaluation of the Sensitivity and Signal Response of the DT-702 LiF:Mg,Cu,P TLD

Abstract

The reliability and accuracy of a radiation dosimetry program is dependent on the intimate knowledge of the characteristics of the dosimetry material. In this study, the effects of pre-exposure (sensitivity) and post-exposure (signal) time on the Navys DT-702/PD (Harshaw Thermoluminescent Dosimeter 8840/41) are evaluated. The results of this study show that the DT-702 TLD has no statistically significant loss of sensitivity or loss of signal with up to 29 weeks of pre-exposure or post-exposure time. Therefore, the DT-702 could be in use for at least 29 weeks producing accurate results without any additional fade correction required.
