Abstract

Abstract: Data from the DBA liquid argon ionization chamber experiment were used to obtain an estimate on the concentration of 42 Ar in the Earth's atmosphere, 9.2 +2.2 -4.6 . 10 -21 atoms of 42 Ar/ atom of 40 Ar. This corresponds to a specific activity of freshly produced liquid argon of 92+ 22 -46 / µ Bq/kg.
