Radiocarbon has been used to define parameters for modeling past, recent, and future CO2/carbon amounts in the atmosphere and in other environmental compartments. In the present paper, we estimate the amount of C-14 in the atmosphere by calculating the molar activity of (CO2)-C-14 (quantity of (CO2)-C-14 molecules per mol of air). Data on the reconstruction of the past concentration of atmospheric CO2 from Antarctic ice cores and Delta C-14 activities from the IntCal09 calibration curve were applied.
