Abstract:

A subset of solid state materials have long been used as integrating dosimeters because they store energy deposited as a result of their interactions with ionizing radiation and then, when stimulated appropriately, release a proportionate amount of visible or near-visible light. During the 1960s, thermoluminescent dosimeters (TLDs), for which heat is used to extract the stored dosimetric signal, began to replace the photographic film as occupational dosimeters of record and for medical dosimetry. At the end of the twentieth century, a viable optically stimulated luminescent (OSL) material was developed which is now gaining in popularity as both an occupational and medical dosimeter. This paper reviews the related stored luminescence processes, presenting a simple conceptual model for optical absorption transitions in OSL materials along with a basic mathematical model for delayed luminescence. The approaches for extracting signal from the OSLs are enumerated.

Abstract:

AbstractGeomorphic analysis and optically stimulated luminescence (OSL) ages from undated Lake Agassiz beaches and adjacent fluvial sediments on Riding Mountain in Manitoba provide insight into their early history. New OSL ages of 14.5±2.4 and 13.4±0.7 ka on the oldest (Herman to Norcross) beaches of Lake Agassiz near the Canada-U.S. border indicate that the Laurentide Ice Sheet (LIS) retreated from that part of the Agassiz basin by ~14.5 ka. To the north along Riding Mountain, the Herman strandlines are absent, and OSL ages on the oldest beach there average 12.9 ka, which links it to the younger Norcross-Tintah strandlines. In adjacent Riding Mountain, OSL ages and geomorphological relationships of a large abandoned glacial spillway >200 m above the oldest beaches of Lake Agassiz indicate that this channel predates retreat of the LIS and formation of beaches in this part of the Agassiz basin, with ice remaining in this area until after 14.5 ka. OSL ages on the Gimli beach 170 km to the east are >3000 yr older than conventional assignments, suggesting that it formed during the Moorhead low-water phase 12.8–10.6 ka. Luminescence ages support the conclusion that the Campbell beach formed ~10.9 ka near the end of the Moorhead low-water phase.

Abstract:

Luminescence, mainly thermoluminescence (TL) and optically stimulated luminescence (OSL), has been researched for more than five decades towards its application to earth and planetary sciences. Luminescence production mechanism has been understood through several theoretical studies, like analytical kinetic theory, numerical models along with the experimental results. Instrument development has progressed with aim from user friendly TL/OSL reader dedicated for dating to challenging reader forin-situMartian sediment dating. Since the development of optical dating in 1985, the technique revolutionised the research in earth sciences. And since then to recent, many methodologies have been developed and some are in developing stage using different signals, like, single grain OSL, red TL, time resolved OSL, thermally transferred OSL (TT-OSL), post infrared-infrared stimulated luminescence (pIR-IRSL), violet light stimulated luminescence (VSL), infrared radioluminescence (IRRL), etc. with an objective to improve the accuracy and precision and to extend the dating range. The wide range of application in different environment, e.g. aeolian, fluvial, marine, glacier, soil, volcanic materials, heated materials, shocked materials, meteorites, etc. have made the technique successful to understand the quaternary history of earth and planetary information like terrestrial and cosmic ray exposure ages of meteorite, meteoroid orbit, thermal metamorphism history of meteorite etc. The aim of this present paper is to discuss some landmarks and recent trends in the development and application in these areas.

Abstract:

AbstractDaylight radiation resets luminescence ‘clock’ to zero on rock surfaces, but transmission depends on the transparency of the rock. On burial, surfaces are no longer exposed to daylight and accumulation of trapped electrons takes place till the excavation. This reduction of luminescence as a function of depth fulfils the prerequisite criterion of daylight bleaching. Thus rock artefacts and monuments follow similar bleaching rationale as those for sediments. In limestone and marble, daylight can reach depths of 0.5–1 mm and up to 16 mm respectively, while for other igneous rocks e.g. quartz in granites, partial bleaching occurs up to 5mm depth under several hours of daylight exposures and almost complete beaching is achieved in the first 1 mm within about 1 min daylight exposure. The ‘quartz technique’ for limestone monuments containing traces of quartz enables their dating with Optically Stimulated Luminescence (OSL) techniques. The surface luminescence (thermoluminescence, TL or OSL) dating has been developed and further refined on various aspects of equivalent dose determination, complex radiation geometry, incomplete bleaching etc. A historical review of the development including important applications, along with some methodological aspects are discussed.

Abstract:

Marble has been used as decorative or building material since ancient times. Various archaeological marble materials of cultural heritage (e.g., statues) are frequently encountered in excavation sites amongst other finds. The scope of the present work is to investigate whether natural marble could be used for dosimetric purposes in cultural applications, such as dating or authenticity test of ancient marble objects, through an integrated experimental approach. For this purpose, the chemical composition, structure/morphology, and luminescence properties of 11 different types of natural marble of different origin (from various geographical regions) were examined by means of micro-x-ray fluorescence spectroscopy, stereoscopic microscopy, thermoluminescence (TL), and optically stimulated luminescence (OSL), respectively. Results indicate that though TL and OSL could be used for the identification of the marble type (origin), the use of natural marble for dosimetric purposes using these methods requires the a-priori knowledge of its type along with some of the main luminescence properties.

Abstract:

A portable fibre optic dosimeter has been developed that uses transparent fluroperovskite dosimeters at the end of a multimode polymer fibre. It uses two stimulation sources that take advantage of the bimodal trap distribution so that the dose rate and cumulative dose can be monitored. Photoluminescence (PL), optically stimulated luminescence (OSL) and radioluminescence (RL) measurements were made on nearly tissue equivalent NaMgF3:Eu2+, NaMgF3:Mn2+, and high sensitivity RbMgF3:Eu2+ and CsCdF3:Mn2+. Initial dose rate and dose measurements were made using our fibre dosimeter during and after exposure to 60 keV gamma rays.

Abstract:

The rapid assessment of radiation dose to members of the public exposed to significant levels of ionizing radiation during a radiological incident presents a significant difficulty in the absence of planned radiation monitoring. However, within most personal electronic devices components such as resistors with alumina substrates can be found that have potentially suitable properties as solid state dosimeters using luminescence measurement techniques. The suitability of several types of ceramic-based components (e.g., resonators, inductors and resistors) has been previously examined using optically stimulated luminescence (OSL) and thermoluminescence (TL) techniques to establish their basic characteristics for the retrospective determination of absorbed dose. In this paper, we present results obtained with aluminum oxide surface mount resistors extracted from mobile phones that further extend this work. Very encouraging results have been obtained related to the measurement of luminescence sensitivity, dose response, reusability, limit of detection, signal reproducibility and known-dose recovery. However, the alumina exhibits a rapid loss of the latent luminescence signal with time following irradiation attributed to athermal (or anomalous) fading. The issues related to obtaining a reliable correction protocol for this loss and the detailed examinations required of the fading behavior are discussed.

Abstract:

Based on radiocarbon and optically stimulated luminescence (OSL) results obtained in the last 5 yr, this paper discusses the absolute chronology of the formation of one of the largest sand dunes within NW Belgium, the Great Ridge of Maldegem-Stekene. Multiproxy analysis of 6 sedimentary sequences points to a complex formation history covering the entire Late Glacial. Dry phases, characterized by eolian deflation and sedimentation, alternated with wet phases in which numerous mostly shallow dune slacks were filled with freshwater. The latter reached their highest water level during the first half of the Allerød, attracting both animals (e.g. European elk) and humans (Federmesser hunter-gatherers). Near the end of the Allerød, all dune slacks finally disappeared as they were filled in with windblown sand ("coversand"), likely forcing prehistoric hunter-gatherers to leave the area.

Abstract:

The piezo-spectroscopic (PS) effect, which may be defined as the shift in wavelength of a spectroscopic transition in a solid in response to an applied strain or stress, may occur both in crystalline and in amorphous structures, regardless of the particular spectroscopic transition involved (e.g., luminescence or Raman spectrum), and independent of the specific mechanism of luminescence emission (i.e., including spectra generated from substitutional impurities, optically active point defects, etc.). The PS effect can be monitored on electro-stimulated spectra when the scale on which the needed characterization lie is of a nanometer length. This effect, being a physical property of the studied material, should be calibrated case by case. The high scanning speed (and computer control) of the electron beam, which can be easily obtained with scan coils, is unsurpassed. Since the most recently developed optoelectronic devices have active areas of submicron dimensions and many of them less than 100 nm, no obvious choice is left but urgently developing an electro-stimulated probe for nano-scale residual stress assessments. In this paper, we show the feasibility of nano-scale stress assessments in the neighborhood of the tip of a crack propagating in GaN, selected as a paradigm semiconductor material.

Resumo: A pesquisa analisa os eventos deposicionais, esculturadores do relevo, na bacia do Ribeirão Entupido, Complexo Alcalino do Passa Quatro, Estado de São Paulo, a partir do estudo dos depósitos recentes da área. Além da análise geomorfológica na referida unidade espacial, a pesquisa buscou estabelecer a idade absoluta de deposição de algumas unidades sedimentares estruturadoras do relevo e os mecanismos envolvidos na sua gênese. Neste contexto, utilizou-se datações por Luminescência Opticamente Estimulada (LOE) e Termoluminescência (TL). Os depósitos sedimentares foram estudados a partir da abordagem morfoestratigráfica. O cruzamento de dados morfoesculturais e morfoestruturais e de datação absoluta permitiu estabelecer quais mecanismos, atuantes ao longo do último milhão de anos, comandaram a morfogênese na bacia em foco. A determinação da morfogênese permitiu definir a susceptibilidade do relevo às mudanças ambientais, inclusive às intervenções antrópicas. Os depósitos sedimentares apresentaram idades vinculadas ao Pleistoceno Superior (61.500 anos) e Holoceno (650 anos) representando, portanto, eventos diferenciados no desenvolvimento e localização deste ambientes. A complexidade da paisagem na bacia do Ribeirão Entupido envolve justamente esta interdigitação de materiais de idades diversas que compõem o mesmo ambiente de deposição, interferindo conjuntamente a tectônica e as condições climáticas, a priori, na espacialização dos depósitos e nas características dos sedimentos.

The dating method of Optically Stimulated Luminescence (OSL) Thermoluminescence (TL) was used in that context.The sedimentary deposits were studied by morphostratigraphic approach. The crossing of mophosculptural and moprostructural data and absoluting dating allow establish wich mechanism, acting through the last million years, commanded the morphogenesis process at the basin.The determination of morfogenesis allowed define the susceptilidy of relief to ambiental changes, including antropic intervention. The sedimentary deposits show ages linked at Up Pleistocene (61.500 years) and Holocene (650 years), showing, therefore, differenced events in development and localization of this environment.The landscape complexity in stream Entupido basin, involves precisely this interdigitation of materials and different ages that compose the same depositional environment, interfering jointly tectonic and climatic conditions, in prior, at specialization of deposits and sedimentary characteristics.

Abstract:

Glacial-interglacial cycles drive changes in the discharge and sediment flux from the headwaters of glaciated basins, which are recorded by proglacial fluvial sediments. Linking braided river stratigraphy to the Quaternary climate record could indicate the control of climate-driven variations in discharge and sediment flux on fluvial processes, and the magnitude and frequency of past climate variations. New Zealand is a key location for investigating terrestrial records of Southern Hemisphere climate change. The Late Quaternary braided river deposits on the Canterbury Plains, South Island, New Zealand have formed over the last 400 ka. The coastal cliff marking the southeastern margin of the Canterbury Plains provides excellent exposure of fluvial sediments deposited during the last glacial period, from ~40 ka until the end of the Last Glacial Maximum (LGM) (~18 ka).Deposition at the modern coastline of the Canterbury Plains is interpreted in the context of the climate event stratigraphy for New Zealand, which requires a precise geochronology. This thesis demonstrates the first successful application of optically stimulated luminescence (OSL) dating to glaciofluvial sediments on South Island: a technique that was previously considered unsuitable for this region. Ages produced for the coastal stratigraphy range from 36.7 ± 2.9 to 18.2 ± 1.3 ka, indicating that deposition took place during the last glacial, with little or no postglacial aggradation. Three adjacent catchments on the southern Canterbury Plains - the Rakaia, Ashburton and Rangitata - have undergone glacial-drainage capture during the period represented by the coastal stratigraphy. During glacials, transfluent ice reversed the flow direction in several key tributaries, resulting in dramatic variations in effective drainage area of the Ashburton and Rangitata, and variations in discharge and sediment flux which are recorded in the stratigraphy of these catchments. The magnitude, timing and duration of drainage capture were quantified using the Plummer and Phillips (2003) glacier model. The Ashburton catchment increased to 160% of the modern effective drainage area when temperature change relative to modern conditions exceeded -6°C during the LGM. Meanwhile, the effective drainage area of the Rangitata decreased to 63%, and the Rakaia to 93%, reducing discharge from these catchments. Furthermore, glaciation dramatically affects the seasonality of the annual hydrograph. At four coastal sites, the fluvial stratigraphy was surveyed to investigate possible variations in depositional architecture, due to both climate variations, and glacial-drainage capture in the Ashburton and Rangitata. Unexpectedly, little vertical variation in depositional architecture was found, indicating that the deposits created by the braided rivers represent sediment transport during a similar set of flow (and by inference, climate) conditions. Laterally extensive erosional surfaces separating storeys of one or two flow depths in thickness, in combination with the OSL geochronology, suggest that the gravel-bed braided river stratigraphy primarily records a response to climate variations within glacial maxima, rather than on the scale of the glacial-interglacial cycle.

Abstract:

Optically Stimulated Luminescence (OSL) is the luminescence emitted from a previously irradiated insulator (or a wide band gap semiconductor) upon exposure to light. The OSL signal intensity is a function of the radiation dose absorbed by the sample and thus can be used as the basis of a radiation dosimetry method. In the literature, OSL studies on natural fluorites are rather limited. In order to promote the material for radiation dosimetry, OSL properties of natural fluorites of different origin were examined in this study. For this purpose, dose-response, reproducibility, thermal stability and fading of the OSL signals were analyzed. In order to find a relation between OSL and TL signals, TL signals and the effect of OSL measurements on TL signals were examined. Thermal activation energies of the light sensitive TL peaks and the OSL signals were also calculated using different methods and the results were compared. Also, absence of the thermal quenching was shown. Finally, TR-OSL signals were measured to have an opinion about the recombination centers. As a result of these studies, it is possible to conclude that natural fluorites show promising features to be used as an environmental dosimeter with regard to a suitable OSL signal, range of linearity, repeatability in response, as well as being readily available at a low cost.

Abstract:

The correlation of x-ray beam quality at typical energies used for dental radiography with dosimeter response was studied. Landauer Luxel Â Optically Stimulated Luminescence (OSL) dosimeters were analyzed for the dose response with respect to the built-in variety of filters in each badge. Trends found in dosimeter response were compared to beam quality measurements through use of a spherical, air ionization chamber and added aluminum filtration to harden the beam. Additionally, a series of image quality analyses were performed to determine if the exposures were performed at optimal settings for easy reading by the dentist. Through the use of a survey in which the dental office sends in the x-ray film to Landauer for analysis, these factors can be determined using calibration curves determined from collected data for correction.

Abstract:

The objective of this study is to perform Optically Stimulated Luminescence (OSL) dating on the ceramic samples from different parts of the Laodikeia by using Infra Red Stimulated Luminescence (IRSL) on polyminerals. As a first step, a literature survey has been done about the dating system and the methodology of dating. The calibration of the system was done before carrying out the experiments. The six ceramic samples were collected from the site and dated. The mineral compositions of the samples were examined by X-ray Diffraction Analysis, which showed that all samples contain quartz, feldspars, calcites and together with other minerals. The equivalent dose was found by using Multiple Aliquot Additive Dose (MAAD) and Multiple Aliquot Regenerative Dose (MARD) techniques using Infra Red diode array of the system that gave the IRSL ages for samples. Alpha counter measured the dose components of uranium and thorium contributions to the annual dose. The potassium concentration was determined by Atomic Emission Spectrometry. The cosmic ray component of annual dose was evaluated by the Al2O3:C Thermoluminescence Dosimeter (TLD) discs which have been placed and kept for 8 and 11 months in the site. From the data the IRSL ages were calculated for six ceramic samples LDKY-1, LDKY-2, LDKY-3, LDKY-4, LDKY-5 and LDKY-6 with the help of the OSL system software. The IRSL ages for these samples, in the given order, are 737 ±

Abstract:

Time Resolved OSL (TR-OSL) is a technique to record the luminescence decay curve data after a brief stimulation pulse and can possibly be used for the separation of luminescence signals from quartz and feldspars. In this study luminescence emission from quartz and feldspar samples was investigated. TR-OSL signals of these samples were studied for the variations with preheating and annealing temperature, stimulation pulse width and total stimulation time, optical bleaching, radiation dose and measurement temperature. TR-OSL decay lifetime of quartz samples was found as ~40 µ
s. Na-feldspar and K-feldspar luminescence signals were deconvoluted using a linear sum of three exponential decays with lifetimes about 45 µ
s, 8 µ
s and 1 µ
s and about 35 µ
s, 7 µ
s and 0.6 µ
s, respectively. Since feldspars signals have a component with lifetime similar to that of quartz (~40 µ
s), luminescence signal separation with TR-OSL seems to be not straightforward.

Abstract:

A combination of two optical methods — Fourier-domain optical coherence tomography (FD-OCT) and photo-stimulated luminescence piezo-spectroscopy (PLPS) is used as a non-destructive evaluation (NDE) tool for thermal barrier coatings (TBC). This research is focused on NDE of electron beam physical vapor deposition (EB-PVD) TBC’s. FD-OCT is an interferometric technique, which uses spectrally broadband visible or infrared light to obtain spectrally resolved interferograms of the light that is back-scattered from subsurface structures and defects (e.g., interfaces, cracks, voids) in optically translucent material. When the Fourier transform is applied to the interferogram, a depth-resolved image of the back-scattering sites is obtained. FD-OCT is shown to be a useful NDE tool that can profile the top coat-metal substrate interface and measure the top coat thickness. Also, it has the potential of assessing microcracking and spallation damage. PLPS provides quantitative information on stress in the thermally grown oxide (TGO) by measuring the spectral shifts in the laser-induced luminescence spectra of the Cr3+ ions present in the TGO. When combined, the PLPS and FD-OCT methods can provide a set of important input parameters for the TBC remaining life predicting model. Ultimately they will collect spatially resolved data on matching spatial domains. The two optical methods are applied to thermally cycled EB-PVD TBC samples. The experimental results are compared to destructive inspection data.

Abstract:

A new generation of Alkaline earth sulfides (MgS, CaS, and BaS) doped with rare-earth ions have been identified by the University of Montpellier as the very high sensitivity of these phosphors, the short time constant of the luminescence and the perfectly separated spectra enable many applications in real time and online dosimetry. The online detecting technology of optically stimulated luminescent (OSL) radiation dosimeter main make use of the OSL characteristics of doping the alkaline-earth metal sulphides, makes the material into the thin films for storing energy from Ionizing radiation, the excitation light through optical fibers reached the where under radiation-field, with a sensitive detection device to read out the radiation dose from storing the OSL material, obtains a novel technology of radiation dose measurement. In the previous works, the dosimeter benefits from a printed circuit board mount. Both the sensor and the electronics are exposed to radiation, the problem of the radiation induced damage is supposedly being addressed. In both cases, the use of optical fibers can provide an elegant solution. Optical fibers offer a unique capability for remote monitoring of radiation in difficult-to-access and hazardous locations. Optical fiber can be located in radiation hazardous areas and optically interrogated from a safe distance. Hence, optical fiber dosemeters are immune to electrical and radio-frequency interference that can seriously degrade the performance of remote electronic dosimeters. In this paper, a novel remote optical fiber radiation dosimeter is described. The optical fiber dosimeter takes advantage of the charge trapping materials CaS:Ce, Sm and SrS:Eu, Sm that exhibit optically stimulated luminescence (OSL). The range of the dosimeter is from 0.01 to 1000Gy. The optically stimulated luminescent (OSL) radiation dosimeter technically surveys a wide dynamic measurement range and a high sensitivity. The equipment is relatively simple and small in size, and has low power consumption. This device is suitable for measuring the space radiation dose; it also can be used in high radiation dose condition and other dangerous radiation occasions.
