Intrinsic superlinear dose dependence of thermoluminescence and optically stimulated luminescence at high excitation dose rates
Superlinear dose dependence of thermoluminescence (TL) and optically stimulated luminescence (OSL) has been reported for many materials. The theoretical explanation has been ascribed to competition of either traps or recombination centers, during the excitation stage or during the read-out phase. There has been an account in the literature on superlinearity of OSL associated with merely one tra...
متن کاملSynthesis and thermoluminescence characterization of combustion derived ZrO2:Ti exposed to beta radiation
Titanium-stabilized Zirconia (ZrO2:Ti) nanoparticles were synthesized by the solution combustion synthesis method. This functional method is used for production of luminescent materials. Ti concentration was between 0.1 to 2 mol %. Nano crystalline tablets of 5 mm diameter and 1 mm thickness were prepared from synthesized powder. The effects of Ti concentration and annealing temperature on the ...
متن کاملEvaluation of Breast Cancer Radiation Therapy Techniques in Outfield Organs of Rando Phantom with Thermoluminescence Dosimeter
Background: Given the importance of scattered and low doses in secondary cancer caused by radiation treatment, the point dose of critical organs, which were not subjected to radiation treatment in breast cancer radiotherapy, was measured.Objective: The purpose of this study is to evaluate the peripheral dose in two techniques of breast cancer radiotherapy with two energies. Methods: Eight diff...
متن کاملMeasurements for dose distribution with a photo- stimulated luminescence dosimeter sheet
Dose distributions for photon beam were measured using a Photo-Stimulated Luminescence Dosimeter (PSLD) sheet, which has 18 x 24 cm dimension and 0.2 mm thickness. Its density and effective atomic number are 1.0 g/cm and 7.6, respectively. The read out was performed by blue LED lights for 20 seconds, which was much shorter than the readout time for TLD. The percent depth dose and dose profile w...
متن کاملEvaluation of Maximum Patient Skin Dose Arising from Interventional Cardiology Using Thermoluminescence Dosimeter in Mashhad, Iran
Introduction The increasing practice of interventional fluoroscopy in diagnosis and treatment of cardiovascular disease has risen attention to improve radiation protection of patients and cardiologists in these relatively high dose techniques. Therefore, nowadays there is an emphasis on the measurement of radiation dose received by patients and cardiologists arising from the relevant procedures...
