Pure and copper doped ZnS nanoparticles in powder form were prepared by wet chemical route method by using thioglycerol as a capping agent. The XRD studies indicate that the samples are cubic in nature. The thermoluminescence (TL) behavior of pure and copper doped ZnS has been studied for fixed 10 min UV exposure time; TL glow curve shows a single peak at 165.1°C and 184.3°C temperature respect...

Radiation effects of photon irradiation in Ytterbium-doped silica optical fibers are still much less explored despite their importance in space-based application as radiation dosimetry. This study investigates and compares the thermoluminescence glow curve, response, linearity and sensitivity of Ytterbium-doped SiO2 optical fibers with that of TLD-100. Samples are placed in solid phantom and ir...

| Astronauts working and living in space are exposed to considerably higher doses and different qualities of ionizing radiation than people on ground. MATROSHKA, a European Space Agency experiment coordinated by the German Aerospace Centre, represents the most comprehensive effort so far in radiation protection dosimetry in space using an anthropomorphic upper torso phantom known from radiother...

PURPOSE To evaluate stochastic and deterministic risks associated with neurointerventional procedures for the patient. METHODS Eight neurovascular interventional procedures were evaluated to determine the entrance skin dose and effective dose for the patient. Dosimetry was done with thermoluminescence dosimeters. The highest dose on the patient's head was recorded as the maximum entrance skin...

background: thermoluminescence dosimetry is one of the dosimetry procedures used widely as routine and personal dosimeters. in order to extend this kind of dosimeters, dental tissue has been examined and was found promising as a tld dosimeter. materials and methods : in this study, 70 health teeth were collected. the only criterion, which was considered for selection of the teeth, was the healt...

Thermoluminescence spectra of manganiferous carbonatite has been studied from 30 1C to 400 1C over the wavelength range from 200 nm to 800 nm. The natural thermoluminescence appears above 200 1C and shows continuous spectral distribution from 240 nm to 800 nm. Above 500 nm the emission appears in the form of line structure emission. These are reproduced by laboratory irradiation which also prod...

In this study, thermoluminescence decay is investigated within Tsallis thermostatistics(TT). We belive that this is the first attempt to handle themoluminescence decay process within TT.
