Thermoluminescence kinetics in materials exposed to the low doses applicable to dating and dosimetry
The goal of this work was to investigate the relevant dosimetric and luminescent properties of MgO:Li3%,Ce0.03%,Sm0.03%, a newly-developed, high sensitivity Optically Stimulated Luminescence (OSL) material of low effective atomic number (Zeff = 10.8) and potential interest for medical and personal dosimetry. We characterized the thermoluminescence (TL), OSL, radioluminescence (RL), and OSL emis...
Achievement of Quality Control Parameters for NIS Personal Thermoluminescence Dosimeter (TLD) System
This work intend to identify and follow up quality control parameters to improve thermoluminescence dosemeter (TLD) system used for personal dosimetry in ionizing radiation metrology laboratory (IRML). Characterization of personal dosimetry system has presented in terms of the stability of reader calibration factors, linearity of response for Cs as reference radiation source, energy and angular...
PURPOSE In 2008, a national intensity modulated radiation therapy (IMRT) dosimetry intercomparison was carried out for all 23 radiation oncology institutions in Switzerland. It was the aim to check the treatment chain focused on the planning, dose calculation, and irradiation process. METHODS A thorax phantom with inhomogeneities was used, in which thermoluminescence dosimeter (TLD) and ioniz...
Important thermoluminescence (TL) properties of five (5) different core sizes Ge-doped optical fibers have been studied to develop new TL material with better response. These are drawn from same preform applying different speed and tension during drawing phase to produce Ge-doped optical fibers with five (5) different core sizes. The results of the investigations are also compared with most com...
