LiF:Mg,Ti (MTT) TL Detectors optimised for high-LET radiation dosimetry

High-dose characterization of different LiF phosphors

“…Three different LiF-based TLDs have been tested: standard LiF:Mg,Ti (denoted MTS), high-sensitive LiF:Mg,Cu,P (MCP) and a recently developed in Kraków version of LiF:Mg,Ti with modified activator composition (MTT) and increased high-LET response (Bilski et al, 2004;Bilski, 2006). All the detectors have been produced at the Institute of Nuclear Physics in Krakow (IFJ).…”

A TLD-based personal dosemeter system for aircrew monitoring

“…Calibrations with high-energy ions of different Z ranging from hydrogen to iron established a HTR vs. LET calibration function ( Figure 1b). Previous successful applications of the HTR method on several space missionsÐincluding measurements on-board space station Mir (7±9) , space shuttles, bio-satellites (10) and the International Space Station (ISS) (11) Ðas well as in radiotherapeutic dosimetry (12) contributed to the acceptance of the method in the international radiation dosimetry community (13,14) . The¯at shape of the HTR vs. LET function in the LET region beyond 100 keV mm À1 and the associated accuracy of the HTR method in the space radiation environment was discussed critically (15) .…”

Long-term fading of LiF:Mg, Cu, P and LiF:Mg, Ti thermoluminescence detectors with standard and modified activator composition

“…Experiment was carried out using three types of TLDs: standard 7 LiF: Mg,Ti (equivalent of TLD-700; denoted MTS-7), MTT-7 (new version of 7 LiF: Mg,Ti with changed activator composition (Bilski et al, 2004) and increased high-LET response, developed for space experiments) and high-sensitive 7 LiF: Mg,Cu,P (MCP-7). All the detectors were 0.6 mm thick, with 4.5 mm in diameter and manufactured at IFJ Krakow.…”
