Abstract
Data from the DBA liquid argon ionization chamber experiment have been used to obtain an estimate on the concentration of 42Ar in the Earth's atmosphere, View the MathML source6.8−3.2+1.7·10−21 atoms of 42Ar per atom of 40Ar corresponding to the 42Ar activity of View the MathML source1.2−0.5+0.3μBq per cubic meter of air.
