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.
