Uncertainties associated with the use of optically stimulated luminescence in personal dosimetry.

This study investigates several sources of uncertainty associated with the application of optically stimulated luminescence (OSL) to personal dosimetry. A commercial OSL system based on Al(2)O(3):C was used for this study. First, it is demonstrated that the concept of repeated evaluation (readout) of the same dosemeter, often referred to as 're-analysis', can introduce uncertainty in the re-estimated dose.

Article Synopsis
- The study investigates how UV-induced bleaching affects deep traps in Harshaw thermoluminescent (TL) materials, specifically LiF:Mg,Cu,P and LiF:Mg,Ti.
- Both materials have maximum readout temperatures (240 °C for LiF:Mg,Cu,P and 300 °C for LiF:Mg,Ti) that can limit the effectiveness of reading trapped doses, particularly after high-dose applications.
- The results show that while optical bleaching effectively reduces residual signals in LiF:Mg,Ti, it does not work for LiF:Mg,Cu,P, which instead benefits from repeatable readout cycles to lower residual signals after high doses.
Technical aspects of the Naval Dosimetry Center quality assurance programme.
Radiat Prot Dosimetry
December 2006
The US Naval Dosimetry Center, Bethesda, MD, USA.
The purpose of this paper is to describe the technical aspects of the Naval Dosimetry Center (NDC) quality programme. The Navy has been formally monitoring personnel for occupational exposure to ionising radiation since at least 1946. The current system, the DT-702/PD, is the Harshaw 8840 holder and 8841 card.
