Thermoluminescence characteristics of natural rhyolite have been studied. Dose response at a wide dose range 0.5–2000 Gy has determined. Minimum detectable and thermal fading rate are evaluated. Glow curve deconvolution is conducted after determining the best read-out conditions. The repeated initial rise (RIR) method used to detect overlapping peaks, glow procedure extract thermoluminescence p...

The colorimetry and thermoluminescence properties of gamma irradiated glass were reported in as early as 1920. The utility of radio-photoluminescence (RPL) of silver activated metaphosphate glass for monitoring high doses of accidental and routine gamma radiation was reported in the 1960s. Since then considerable amount of research work has been carried out to study the thermoluminescence (TL),...

BACKGROUND AND PURPOSE Volume-of-interest C-arm CT is a novel technique for imaging of intracranial high-contrast objects. We performed this study to evaluate the potential diagnostic value and radiation dose reduction of this technique for imaging of intracranial stents and flow diverters. MATERIALS AND METHODS Twenty-seven patients were imaged with a VOI C-arm CT scan following treatment wi...

Thermoluminescence (TL) studies of insulators, including crystals of minerals such as calcite, quartz or zircon, have resulted in the development of a wider range of applications in the fields of radiation dosimetry and archaeological and geological dating. Most conventional TL measurements are made by recording light emission during heating by means of broad-band optical filters and blue-sensi...

BACKGROUND Accelerated partial breast irradiation via interstitial balloon brachytherapy is a fast and effective treatment method for certain early stage breast cancers however skin, chest wall and Lung doses are correlated with toxicity in patients treated with breast brachytherapy. OBJECTIVE To investigate the percentage of the dose received by critical organ (skin), thermoluminescence dete...

Carbon and magnesium co-doped aluminum oxide (Al2O3:C,Mg) is a highly sensitive luminescence dosimeter with promising use in wide spectrum of radiation-related applications, including neutron dosimetry as fluorescent nuclear track detector (FNTD). The goal this work to critically evaluate diverse methods approaches for the determination kinetic parameters using Al2O3:C, Mg case study. was beta ...
