説明
<jats:p>The definitive paper by Stuiver and Polach (1977) established the conventions for reporting of radiocarbon data for chronological and geophysical studies based on the radioactive decay of <jats:sup>14</jats:sup>C in the sample since the year of sample death or formation. Several ways of reporting <jats:sup>14</jats:sup>C activity levels relative to a standard were also established, but no specific instructions were given for reporting nuclear weapons-testing (post-bomb) <jats:sup>14</jats:sup>C levels in samples. Because the use of post-bomb <jats:sup>14</jats:sup>C is becoming more prevalent in forensics, biology, and geosciences, a convention needs to be adopted. We advocate the use of <jats:italic>fraction modern</jats:italic> with a new symbol F<jats:sup>14</jats:sup>C to prevent confusion with the previously used Fm, which may or may not have been fractionation-corrected. We also discuss the calibration of post-bomb <jats:sup>14</jats:sup>C samples and the available data sets and compilations, but do not give a recommendation for a particular data set.</jats:p>
