Fabrication of Annealing Equipment for Optically Stimulated Luminescence (OSL) Dosimeter

Japanese Journal of Radiological Technology, 2014
The optically stimulated luminescence (OSL) dosimeter is a useful detector for measuring absorbed doses of X-rays. A small-type OSL dosimeter, "nanoDot", has recently been developed by Landauer, Inc., who also manufacture "microStar" reading equipment.

Luminescence properties of common salt (NaCl) available in Nigeria for use as accident dosimeter in radiological emergency situation

Journal of Radiation Research and Applied Sciences, 2017
In the event of a radiological accident or attack, it is important to assess and quantify radiation dose to the population. This could be done using materials in the vicinity that are sensitive to ionizing radiation.

Optically stimulated luminescence (OSL) as a chronometer for surface exposure dating [PDF]

Journal of Geophysical Research: Solid Earth, 2012
We pioneer a technique of surface‐exposure dating based upon the characteristic form of an optically stimulated luminescence (OSL) bleaching profile beneath a rock surface; this evolves as a function of depth and time. As a field illustration of this new method, the maximum age of a premier example of Barrier Canyon Style (BCS) rock art in Canyonlands ...

Thermally Transferred Optically Stimulated Luminescence, TT-OSL: a study on the responsible traps

Journal of Physics: Conference Series, 2022
Abstract Aim of this paper is to better investigate the Thermally Transferred Optically Stimulated Luminescence (TT-OSL) signal generated in quartz samples, both mineral quartz and quartz extracted from sediment, when they are heated after an optical bleaching. In recent years, TT-OSL has become an interesting dating technique because it
