Thermoluminescence behavior of basaltic rocks collected in southeastern region of Turkey

Thermoluminescence in pumice stone collected from the Mediterranean coast

“…[39] However, a high radiation dose may cause deformation of the main trap structure because TL peak temperature shifts to a higher temperature region at 80 C in the dose interval 2.4Gy to 4.6 kGy. The pumice stone used in this study had a wide linear dose-response region, between 2.4 Gy and 144 Gy, as reported in the study by Toktamis ¸et al [34] The doseresponse of any dosimetric material describes the TL yield as a function of dose and a wide linear region for the dose-response is desirable in a dosimetric material. Reusability is a necessary parameter for a dosimeter.…”

“…Quartz is a very abundant mineral, and its TL dosimeter properties have been investigated by several researchers. [20,21,[32][33][34][35] Guérin and Samper [36] studied primary volcanic quartz for its aberrant TL dates. Although there have been many published studies on TL properties, each quartz mineral extracted from different regions of the world may exhibit different properties.…”

“…In the present study, the pumice stone had a good TL glow curve with an obvious, wide peak at 200 C. A similar TL glow curve was observed for basalt, which is well known as an extrusive igneous rock that erupts onto land following volcanic eruption. [34] The common point of pumice and basalt is that they are volcanic rock (igneous rock) that forms when magma suddenly depressurizes and cools and that one of their main constituents is quartz (SiO 2 ). The wide peak is the accumulation of several individual satellite peaks that represent charged carrier traps close together in the forbidden band gap of the sample.…”
