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.

Centennial- to millennial-scale hard rock erosion rates deduced from luminescence-depth profiles [PDF]

, 2018
The measurement of erosion and weathering rates in different geomorphic settings and over diverse temporal and spatial scales is fundamental to the quantification of rates and patterns of earth surface processes. A knowledge of the rates of these surface

Optically stimulated luminescence from BeO ceramics: An LM-OSL study

Radiation Measurements, 2010
Abstract Optically Stimulated Luminescence (OSL) signals of BeO ceramics were investigated using continuous wave (CW) OSL and Linearly Modulated (LM) OSL. It was found that both curves can be approximated using a linear combination of two first-order components.
