Table 5.

Average F14C Values of Solids and Water-Soluble Fractions of Control and Archived Spores. The averages and standard deviations of the F14C values are calculated from values in Table 4. The estimated age range of the soluble fraction is based on the published atmospheric record [3–7] and recent measurements at LLNL.
