Radioluminescence (RL, i.e. prompt luminescence emitted during exposure to ionizing radiation) is used for analysing luminescence emission processes and has been proposed as a method for determining received radiation doses in both natural and synthetic radiation dosimeters, We describe here an automated system capable of both multi-sample RL analysis and comparative studies using traditional thermoluminescence (TL) and optically stimulated luminescence (OSL) methods. The radioluminescence unit is intended as an attachment for the existing automated Riso TL-OSL systems; it delivers a dose rate of 4.5 Gy/min to materials such as quartz, using an 80 mCi Sr-90/Y-90 beta -source. The unit enables the measurement of RL in the temperature range 25-500 degreesC using both continuous and pulsed radiation exposures. Measurements are fully automated, allowing up to 48 samples to be measured in any one experimental run. Results from several experiments are presented for two representative dosimeters; natural quartz and artificial Al2O3:C. These experiments include investigation of the dose and temperature dependence of RL, pulsed RL, and spectrally resolved RL; comparisons with TL are also made.

Synthesis and characterization of lithium tetraborate and lithium triborate phosphors doped with metals and their thermoluminescence properties Çelik, Muzaffer Gençay; Yılmaz, Ayşen; Department of Chemistry (2016) The phenomenon of thermoluminescence (TL) has been interested in the measurement of radiation dose over the past few decades. Thermoluminescence property of a material can be used in surface acoustic wave apparatus, sensor sector and non-linear optics (LASER). Moreover, in dosimetry TL concept has been utilized. Thermoluminescence dosimetry is interested in the fields of environmental, personnel, and clinical radiation applications. In this thesis, dosimetric phosphors lithium tetraborate (Li2B4O7: LTB) [1]...
An approach to measure trace elements in particles collected on fiber filters using EDXRF ÖZTÜRK, FATMA; Zararsız, Abdullah; Kırmaz, Rıdvan; Tuncel, Süleyman Gürdal (2011-01-15) A method developed for analyzes of large number of aerosol samples using Energy Dispersive X-Ray Fluorescence (EDXRF) and its performance were discussed in this manuscript. Atmospheric aerosol samples evaluated in this study were collected on cellulose fiber (Whatman-41) filters, employing a Hi-Vol sampler, at a monitoring station located on the Mediterranean coast of Turkey. between 1993 and 2001. Approximately 1700 samples were collected in this period. Six-hundred of these samples were analyzed by instru...
The Development of bifacial dye sensitized solar cells based on binary ionic liquid electrolyte Coşar, Mustafa Burak; Özenbaş, Ahmet Macit; Department of Metallurgical and Materials Engineering (2013) In this study, we investigated the effect of electrolyte composition, photoanode thickness, and the additions of GuSCN (guanidinium thiocyanate), NMB (N-methylbenimidazole), and SiO2 on the photovoltaic performance of DSSCs (dye sensitized solar cells). A bifacial DSSC is realized and irradiated from front and rear sides. The devices give maximum photovoltaic efficiencies for 70% PMII (1-propyl 3-ethylimidazoliumiodide)/30%(EMIB(CN)4)(1-ethyl-3-methyl-imidazolium tetracyano borate) electrolyte composition a...
Beta Dosimetry Using Thin Layer a Al2O3 C TL Detectors GÖKSU, HAYRİYE YETER; Bulur, Enver; WAHL, W (1999-01-01) The possibility of using thin-layer alpha-Al2O3:C thermoluminescence detectors (TLD) for the measurement of the annual beta dose from natural materials, considered for retrospective luminescence dosimetry, archaeometry and authenticity testing was checked. The annual beta doses from various materials including some porcelains, bricks and soils were determined by storing the detectors underneath the samples in a shielded environment for a period of time. Beta doses from two feldspar standards NBS 70a and NBS...
An optical fiber radiation sensor for remote detection of radiological materials Klein, DM; Yukihara, EG; Bulur, Enver; Durham, JS; Akselrod, MS; McKeever, SWS (Institute of Electrical and Electronics Engineers (IEEE), 2005-08-01) This paper demonstrates the feasibility of a portable radiation sensor system that uses the pulsed optically stimulated luminescence technique to remotely interrogate an aluminum oxide (Al2O3:C) radiation sensor via an optical fiber. The objective is to develop a system for applications requiring simple and inexpensive sensors for widespread monitoring of ionizing radiation levels, which can be remotely interrogated at regular periods with little or no human intervention and are easy to install, operate, an...
