The optically stimulated luminescence (OSL) dating method promises to provide reliable ages for various Quaternary archives. Coastal sedimentation in the Bohai Sea (northeastern China) since Middle Pleistocene has been influenced by paleoenvironmental and sea-level change, of which restricted using OSL approach multiple investigations. In this study, establish a robust chronological framework c...

An association between salt pans or dry lake beds and distinctive crescentic lake-floor sand mounds (1–10 m high, tens to hundreds of metres wide) is commonplace in desert systems. In the Makgadikgadi Basin northern Botswana, a debate about formative processes these landforms has persisted despite numerous morphometric, sedimentary geochronological analyses, with mound variously inferred be aeo...

Abstract For 3D optically stimulated luminescence (OSL) based dosimeters to be clinically applicable, certain standards must met. Among these are low detectable doses with high accuracy and precision, ideally comparable those of point-like detectors. By investigating a model the central part an OSL readout-system, we present estimate <?CDATA $\sim 4\cdot {10}^{7}\frac{{\rm{photons}}}{{\rm{Gy}}\...

We investigated the optically stimulated luminescence (OSL) and thermoluminescence (TL) characteristics of quartz from sediments parent rocks across South America. OSL TL sensitivities were compared with characteristic dose response curves. Additionally, we estimated electron trap parameters contrasting sensitivities. Our results show that natural (initial 0.8 s) (110 °C peak) are positively co...
