We report on a case study of radiocarbon (14C) measurements applied to three pairs of tusks from African elephants, which were supposedly hunted in the 1960s in Tanzania and/or Kenya. The 14C results of 1.40 to 1.60 F14C fall into 14C bomb peak values between 1960 and 1975, thus confirming the suspected hunting time. Since the trading of ivory from African elephants killed after 1989 was banned by the international CITES convention, the investigated tusks are not affected by this ban.

非洲象牙的14C炸弹峰值分析及其与Cites的关系

我们报告了一个放射性碳的案例研究（14C) 测量适用于来自非洲象的三对象牙，这些象牙据说是在 1960 年代在坦桑尼亚和/或肯尼亚被猎杀的。这14C 结果为 1.40 至 1.60 F14C 陷入14C弹在1960年至1975年间的峰值，从而证实了可疑的狩猎时间。由于国际 CITES 公约禁止交易 1989 年后被猎杀的非洲象的象牙，因此被调查的象牙不受该禁令的影响。
