Relative response of TL and component-resolved OSL to alpha and beta radiations in annealed sedimentary quartz
(Pergamon-Elsevier Science Ltd, 2011-10)
Knowledge of the relative luminescence response to alpha and beta radiation is very important in TL and OSL dating. In the present study the relative alpha to beta response is studied in a sedimentary quartz sample, ...
In-homogeneity in the pre-dose sensitization of the 110 degrees C TL peak in various quartz samples: The influence of annealing
(Elsevier Science BV, 2012-03-01)
The pre-dose sensitization effect of the 110 degrees C TL glow-peak of quartz is a basic tool in thermoluminescence and optically stimulated luminescence dating and retrospective dosimetry. In the present work, a homogeneity ...
Thermoluminescence as a probe in bioactivity studies; the case of 58S sol-gel bioactive glass
(IOP Publishing Ltd, 2011-10-05)
The formation of a carbonated hydroxyapatite (HCAp) layer on the surface of bioactive materials is the main reaction that takes place upon their immersion in physiological fluids. To date, all techniques used for the ...
Temperature lags of luminescence measurements in a commercial luminescence reader
(Elsevier Science Inc, 2015-09-15)
The temperature recorded in thermoluminescence and optically stimulated luminescence equipments is not the temperature of the sample but that of the heating element on which the thermocouple is attached. Depending upon the ...
Dating fossil root cast (Black Sea coast, Turkey) using thermoluminescence: Implications for windblown drift of shelf carbonates during MIS 2
(Elsevier Ltd., 2016-05-16)
Rhizoliths are mostly sub-aerially exposed root prints which appear through removal of the rock units that cap them. A horizontal-lying residual of a rhizolith, consisting purely of soft inner core material of white color ...
Thermal quenching of thermoluminescence in quartz samples of various origins
(Univ Agean, Dept Mediterranean Stud, 2010)
The effect of thermal quenching plays an important role in the thermoluminescence (TL) of quartz on which many applications of TL are based. In present work it is investigated that the thermal quenching parameters i.e. the ...
The correlation of fast OSL component with the TL peak at 325 degrees C in quartz of various origins
(Elsevier Science BV, 2010-02)
The fast component of the optically stimulated luminescence (OSL) signal in quartz is the basic tool for the optical dating. Its relation with the thermoluminescence (TL) glow-peak at about 325 degrees C is well established ...
Investigation of the OSL signal from very deep traps in natural quartz
(Univ Agean, Dept Mediterranean Stud, 2010)
It has been recently reported by several studies that a thermally transferred optically stimulated luminescence (TT-OSL) signal from quartz grains can be used to extend the dating range for quartz samples. The TT-OSL signals ...
IRSL dating of a deep water core from Pylos, Greece; comparison to post ir blue OSL and TL dating results
(Univ Agean, 2011)
The 'double SAR' protocol procedure permits the determination of two equivalent dose (De) values for each polymineral aliquot; an IRSL De resulting mostly from feldspars along with a post-IR OSL De for a mixed signal for ...
Dissolution and subsequent re-crystallization as zeroing mechanism, thermal properties and component resolved dose response of salt (NaCl) for retrospective dosimetry
(Pergamon-Elsevier Science Ltd, 2011-09)
In the present study we report dosimetric properties of iodized salt aiming at using it as an accidental luminescent dosimeter. It was found that the very good sensitivity of its main dosimetric peak is strongly affected ...
