radiocarbon age

基本解释

Radiocarbon dating showed that the head's age matched the king's date of death.
放射性碳显示这个头颅的年龄符合国王的死期。
The shroud was also damaged by a fire in the Late Middle Ages which could have added carbon material, resulting in a higher radiocarbon content and a later calculated age.
这块裹尸布在中世纪后期遭到火灾破坏，也可能会增加另外的碳元素，这样会产生高放射性的碳素使计算的年代有所延迟。
Because we know how fast radiocarbon decays, we can figure out the age of the organic material.
因为我们知道放射性碳分解有多快，我们就能计算出有机材料的年龄。

Using a combination of modern physics tools--including three-dimensional, high-resolution X-ray, radiocarbon dating with accelerator mass spectrometry, and infrared spectroscopy--the researchers analysed the tooth to determine the age and composition of a resinous filling detected inside.
