Abstract
An important constraint on the reliability of cosmogenic nuclide exposure dating is the rigorous determination of production rates. We present a new dataset for Be-10 production rate calibration from Mount Billingen, southern Sweden, the site of the final drainage of the Baltic Ice Lake, an event dated to 11,620 +/- 100 cal yr BP. Five samples of flood-scoured bedrock surfaces (58.5 degrees N, 13.7 degrees E, 105-120 m a.s.I.) unambiguously connected to the drainage event yield a reference Be-10 production rate of 4.19 +/- 0.20 atoms g(-1) yr(-1) for the CRONUS-Earth online calculator Lm scaling and 4.02 +/- 0.18 atoms g(-1) yr(-1) for the nuclide specific LSDn scaling. We also recalibrate the reference Be-10 production rates for four... (More)

We also recalibrate the reference Be-10 production rates for four sites in Norway and combine three of these with the Billingen results to derive a tightly clustered Scandinavian reference Be-10 production rate of 4.13 +/- 0.11 atoms g(-1) yr(-1) for the CRONUS Lm scaling and 3.95 +/- 0.10 atoms g(-1) yr(-1) for the LSDn scaling scheme.
