Understanding The Influence of Photon Energy On 6Mv Non Reference Dosimetry and Ct Dosimetry Using Tld and Osld
… and optically stimulated luminescent dosimeters (OSLD).</p> <p>There were two main objectives to this work. The first objective was to evaluate the energy dependence of TLD and OSLD for non-reference measurement conditions in a radiotherapy environment. The second objective was to fully …

Development and Implementation of The Use of Optically Stimulated Luminescent Detectors In The Radiological Physics Center Anthropomorphic Quality Assurance Phantoms
… to optically stimulated luminescent dosimeters (OSLDs), but a problem lies in the angular dependence exhibited by the OSLD. The purpose of this study was to characterize the angular dependence of OSLD and establish a correction factor if necessary, to provide accurate dosimetric measurements as a …

Characterization of Oslds For Use In Small Field Photon Beam Dosimetry
… optically stimulated luminescence dosimeters (OSLDs) whose visible active luminescent area has been masked. The phantom has two measurement points with two OSLDs at each location and a film insert for localization purposes only. The masked OSLDs were characterized accounting for various …

Development of A Remote Dosimetric Audit Framework For Carbon Therapy
… and optically-stimulated luminescent dosimeters (OSLD) and GafChromic film.</p> <p>The aim of this work will be to characterize dosimeters and materials for use in carbon radiotherapy and combine these tools to create an end-to-end anthropomorphic phantom audit. The absorbed dose corrections …

Measuring terrestrial wildlife external radiation exposure under field conditions
… to identify four passive dosimeters (i.e. TLD, OSLD, RPLD and DIS), which should be suitable for reindeer. To protect these dosimeters during use, they were housed in an aluminium box that could be attached to a collar around the reindeer’s neck. The performance of dosimeters within the box was …

Extending The Lifetime of Optically Stimulated Dosimeters For Use In Output Checks At Iroc- Houston
… Optically Stimulated Luminescent Dosimeters (OSLDs) are a prominent form of in-vivo dosimeter used both in clinics as well as for the audits of radiological<br />equipment at the Imaging and Radiation Oncology Core (IROC)-Houston. These<br />dosimeters have a recommended dose limit of 10 Gy …
