Sand—a high gamma dose thermoluminescence dosimeter

Descalvado sand for high-dose dosimetry

“…Several kinds of dosimeters have been proposed, tested, and are presently in use for this purpose (McLaughlin et al, 1989). Propositions of dosimetric material easily found in the nature, as sand or commercial products as glass, were already studied (Vaijapurkar and Bhatnagar, 1993;Vaijapurkar et al, 1998;Quezada and Caldas, 1999;Caldas and Teixeira, 2002;Rodrigues and Caldas, 2002;Caldas et al, 2006).…”

Influence of thermal treatments on the response of sand radiation detectors for high-dose dosimetry

“…Sand is mainly constituted of quartz and feldspar, presenting the phenomenon of thermoluminescence (TL). Sand also contains some other elements in smaller amounts (2,3) . The group of silicates represents one type of material of greatest amount and importance in the world.…”

An investigation of the dosimetric and kinetic properties of sand using ESR and TL techniques

“…In the literature similar glow curve shapes and glow peak temperature values were also observed for different samples (Ogundare et al, 2006;Franklin et al 1995;Soliman and Salama 2009). On the other hand, there are also different glow curves given in the literature for previously studied sand samples (Vaijapurkar et al, 1998;Caldas et al, 2006;Benny and Bhatt, 1996).…”

“…The previous studies on natural sand sample indicated different glow peaks at different temperature (Vaijapurkar et al, 1998;Pitalua et al, 2013). On the other hand, a similar TL glow curve centered at about 315°C was also observed for natural sandstone by Soliman and Salama (2009) .…”

“…The concentration of impurity-related defects is dependent on the conditions of mineral formation or subsequent alteration (Preusser et al, 2009). In spite of complex TL glow curve; there have been more TL studies on this subject than those on ESR in the literature (Benny et al, 1997(Benny et al, , 2000Vaijapurkar et al, 1998;Soliman and Salama, 2009;Pitalua et al, 2013;Pandya et al, 2013).…”
