New radiocarbon (14C) dates we obtained in our radiocarbon laboratory equipped with a liquid scintillation counter using BGO (Bi4Ge3012) tubes. The electronic stability of the counter gave a background below 0.2 cpm. Our 14C dates agree well with the interpretations done for the samples. Most of the results in these analyses were obtained on shell samples, charcoal samples, and tree leaves. Calibration of the dates with the appropriate software (Calib 7.0.4) allows better interpretation of the results and their importance in the studied regions. In this paper, we present 14C results from archaeological and environmental sites in Senegal, Mali, and Togo and report the results in our second laboratory date list.
