In this study the dosimetric properties of alumina (Al 2 O 3) substrates found in resistors retrieved from mobile phones were investigated.Measurements of the decline of optically stimulated luminescence (OSL) generated following exposure of these substrates to ionising radiation showed that 16% of the signal could still be detected after 2 years (735 days). 2018-05-30 Optically Stimulated Luminescence or OSL is the most advanced technology developed by Landauer, Inc. for measuring radiation exposure. Compared to thermoluminescence dosimeters (TLD), which are heated to determine the radiation exposure, OSL dosimeters are exposed to a light source to obtain the amount of radiation absorbed by the dosimeter. Aim: The modern radiotherapy techniques impose new challenges for dosimetry systems with high precision and accuracy in in vivo and in phantom dosimetric measurements.

Abstract. The application of optically stimulated luminescence (OSL) for use in radiation dosimetry is reviewed. A broad description is given of OSL techniques developed at Riso National Laboratory and at Oklahoma State University, and recent collaborative investigations on the properties of a variety of natural and synthetic materials are reported.

It is found that the peak wavelength of the optically stimulation spectrum is about 690 nm. This result suggests that the semiconductor laser can be used as the stimulating light source. Here we introduce new precipitation proxies based on optically stimulated luminescence and thermoluminescence signals of quartz and feldspar. The rationale is that when precipitation changes over the catchment through time, different sediment sources regarding weathering intensity and parent rock types are drained, supplying sediments with varying signals of luminescence to the ocean. The OSL dosimetry (Optically Stimulated Luminescence) is a method that has established itself in the whole-body dosimetry. As can be deduced, this method is based on optically stimulated luminescence.The OSL dosimeter provides a very high degree of sensitivity by giving an accurate reading as low as 1 mrem for x-ray and gamma ray photons with energies ranging from 5 keV to greater than … 2015-08-01 2020-03-30 In this paper main optically stimulated luminescence (OSL) and thermoluminescence (TL) characteristics are presented of a newly synthesised material MgO doped with terbium (Tb) developed at the Institute of Nuclear Science, Vinca.

Luminescence dating refers to a group of methods of determining how long ago mineral grains were last exposed to sunlight or sufficient heating. It is useful to geologists and archaeologists who want to know when such an event occurred. It uses various methods to stimulate and measure luminescence. It includes techniques such as optically stimulated luminescence, infrared stimulated luminescence, and thermoluminescence dating. "Optical dating" typically refers to OSL and IRSL, but
OSL assumes that minerals were both constantly and sufficiently exposed to oxygen before being buried, noticeably bleaching the observed mineral or fossil. Optically stimulated luminescence (OSL) is one of the many known stimulated phenomena in condensed matter that can be induced by ionizing radiation and that became a successful practical tool in radiation dosimetry. Until recently thermo-luminescence (TL) dosimetry (TLD) was the most popular dosimetric technique when relatively inexpensive passive inte- This article presents optically stimulated luminescence (OSL) ages from (1) ice-marginal glaciofluvial sands on Riding Mountain; (2) beaches of Lake Agassiz along the eastern side of Riding Mountain; (3) beaches to the south near Morden, Manitoba, which lie along the Manitoba Escarpment; and (4) a lower beach ridge 175 km to the east of Riding Mountain.
