Comment on "Radiation History of Fossil Meteorites from Sweden" by V.A. Alexeev (2010), Solar System Research, 44, 311-319

Summary, in English

We dispute the claim by Alexeev (2010) that the numerous fossil meteorites found in mid-Ordovician sediments in southern Sweden can be explained by a single large meteorite shower some 470 million years ago, and-in particular-that the reported variable cosmic ray exposure ages derived from cosmogenic Ne-21 in chromite grains extracted from the fossil meteorites actually reflect variable contributions of nucleogenic Ne-21 instead.
