Abstract

A method of measurement of specific 10Be contents of naturally occurring materials is described. The method is based on mass spectrometry of 10Be/9Be ratios, using the Rutgers-Bell tandem van de Graaff accelerator. The detection limit is currently approximately 107 atoms 10Be, and the precision, when not limited by counting statistics, is 13%. The linear proportionality of observed 10Be/9Be ratio to actual ratio in sample has been verified within uncertainty over more than two orders of magnitude in ratio. Results are presented for the application of the method to determination of 10Be contents of six samples from various locations in the Antarctic H-chondrite ALHA 78084. No significant variations among the samples due to differences in shielding from cosmic rays were observed. © 1982.
