Feldspar as a retrospective dosimeter is receiving more and more attention because of its useful luminescence properties; in particular the dose response curve extends to significantly higher doses than quartz. However, feldspars have one major disad

Optically stimulated luminescence (OSL) has been used for estimation of the accumulated doses in quartz inclusions obtained from two fired bricks, extracted in July 2004 from a building located in the forested surroundings of the recreational area No

Natural sediments usually contain a mix of quartz and feldspar. Because these two minerals have different luminescence properties and record different natural doses it is normally necessary to physically separate them before measurement. This paper i

The knowledge of environmental dose rate on Mars is crucial for in situ Optically Stimulated Luminescence (OSL) dating of martian sediments. Protons are the dominant source of dose rate on Mars. The efficiency of OSL production after proton irradiati

We determine the burial dose in three known-age incompletely bleached fluvial samples using single grains of quartz. Estimation of burial dose in incompletely bleached samples requires that the characteristics of the well-bleached part of the distrib

An optically stimulated luminescence (OSL) age obtained from a Japanese tephra using quartz phenocrysts severely underestimated the known age. The characteristics of the OSL signals were investigated in order to understand the cause of the underestim

Determination of equivalent doses in retrospective dosimetry involves calibration by irradiation of the dosimeters in the laboratory. In the Riso TL/OSL measurement system, laboratory irradiations make use of a radionuclide ( 90 Sr/ 90 Y beta) source
