Calibration of F14C results for bio-oil sample-3 (A) and the pistachio shell reference sample (B) and Ox Cal v.4.4 (Bronk Ramsey, 2009) using the post-bomb atmospheric NH1 curve (Reimer et al., 2004; Hua et al., 2022). The F14C values are used commonly in the calibration process, and the relation to pMC is pMC = F14C*100 (Stenström et al., 2011). pMC, percent modern carbon.
