Description
Accelerator mass spectrometry analysis of 10Be concentrations in ~1.5 mg split of "stone of interest", OREX-800023-9. The sample was dissolved in HF/HNO3 and a small aliquot of the dissolved sample was taken for chemical analysis by ICP-OES. The 10Be concentration in the sample (8.4 dpm/kg) is similar to the concentration of ~8 dpm/kg in the aggregate sample, indicating that the stone of interest and aggregate samples had similar cosmic-ray exposure histories on the surface of Bennu.
