Onyx Samples Characterization by Osl Technique for High-dose Dosimetry
Onyx samples were studied in this work to verify their dosimetric properties. The Onyx stone is considered nobler than marble. At IPEN, the radiation metrology group has studied new materials for application in highdose dosimetry. The Onyx samples were exposed using a Gamma-Cell 220 system ( 60 Co), for doses of 50 Gy up to 300 kGy. The lower detection doses, the reproducibility of the OSL resp...
متن کاملAdvantages and Disadvantages in the Utilisation of Thermoluminescence (tl) and Optically Stimulated Luminescence (osl) for Radiation Dosimetry
Thermoluminescence is an established method for radiation dosimetry as well as retrospective dosimetry. In spite of its great success, different difficulties are associated with its application. These include anomalous fading, changes in the properties of the sample due to its heating in the readout phase, including a sensitization due to the combined effect of irradiation and heating and non-l...
متن کاملRadiotherapy dosimetry using a commercial OSL system.
A commercial optically stimulated luminescence (OSL) system developed for radiation protection dosimetry by Landauer, Inc., the InLight microStar reader, was tested for dosimetry procedures in radiotherapy. The system uses carbon-doped aluminum oxide, Al2O3:C, as a radiation detector material. Using this OSL system, a percent depth dose curve for 60Co gamma radiation was measured in solid water...
متن کاملA Simple Method to Separate Quartz and Feldspar and Its Application to Tl/osl Methods
In the dating of sediments by luminescence methods, to obtain a sample the purest possible as to its mineralogy determines the rest of the analytical procedures. The isolation of the sample minerals is a critical stage due to the impossibility of quantifying the relative contributions to the dose from the different minerals. In this paper we propose a non chemical method to isolate quartz from ...
متن کاملDevelopment of Osl Reader Systems for Radiation Dosimetry
Thermoluminescence (TL) and optically stimulated luminescence (OSL) techniques are known as a research tools for the study of phosphor materials and for their applications in radiation dosimetry in particular [1]. Although TL technique is known since several decades, OSL is relatively newer technique. The TL or OSL emission from an irradiated sample arises upon stimulation with heat or light re...
