relative concentration of radiocarbon ¹⁴C expressed as a counting of β-irradiation from the decayed radiocarbon atoms per minute

Note 1

The unit of ¹⁴C activity is “dpm” (decay per minute).

Note 2

The ¹⁴C activity is determined relatively using standard reference material (SRM 4990c) whose ¹⁴C activity is set at 13,56 dpm.
