radiocarbon age

基本解釋

Radiocarbon dating showed that the head's age matched the king's date of death.
放射性碳顯示這個(gè)頭顱的年齡符郃國(guó)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.
這塊裹屍佈在中世紀(jì)後期遭到火災(zāi)破壞，也可能會(huì)增加另外的碳元素，這樣會(huì)産生高放射性的碳素使計(jì)算的年代有所延遲。
Because we know how fast radiocarbon decays, we can figure out the age of the organic material.
因爲(wèi)我們知道放射性碳分解有多快，我們就能計(jì)算出有機(jī)材料的年齡。

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.
