Reported 14C activities are usually connected to radiocarbon amount in the carbon isotopic mixture. Our paper is aimed on estimation of 14C/14CO2 amount in the atmosphere (and its trend), utilizing calculation of a 14C activity concentration. A parameter connected only with a 14C quantity in the volume or mass unit of air is not influenced by a fossil carbon amount. Such a “robust” parameter can be influenced only by processes connected with 14C emissions/depositions.
