Table 1 Summary data of luminescence dating giving sample code and depth, number of repeated measurements (n), concentration of dose rate relevant elements (K, Th, U), present sediment moisture and water content used for dose rates (D F = dose rate feldspar, D Q = dose rate quartz), equivalent dose (ED) for feldspar IRSL and quartz OSL and resulting ages

From: A ~180,000 years sedimentation history of a perialpine overdeepened glacial trough (Wehntal, N-Switzerland)

  1. Radioactive disequilibrium in the 238U decay chain was observed for four samples (a–d, NWG 1, 6, 8, 12) but these had a negligible effect on dose rate determination
  2. U-238 from l86 keV: a 7.63 ± 1.14 ppm; b 6.30 ± 1.18 ppm; c 3.34 ± 0.46 ppm, d 4.65 ± 0.80 ppm
