What can radiocarbon dating be used on

Its essentially like slowly burning the sample, so we can just oxidize a little off the surface and collect that carbon dioxide, explains Rowe.

According to researchers at Queens University of Belfast, the new curve doubles the accuracy of dating as well as the age of artifacts on which it can be used, from 25,000 to 50,000 years.

A number of stories are commonly circulated about a shell, or a piece of coal, or some other sample which supposedly yielded a radiocarbon date which could not possibly be correct.

Such stories misrepresent the truth and do a disservice to science and public knowlege.

Thus far, hes dated samples of wood, charcoal, animal skin, bone from a mummy, and ostrich eggshell. Taylor, a radiocarbon expert at the University of California, Riverside, says Rowes technique may have limitations, as items older than 10,000 years will have impurities that the technique may not be able to purge.

Everything so far that weve tried to do with the nondestructive technique has agreed statistically with regular radiocarbon dating, Rowe says, and you basically dont see any change in the sample. Archaeologists, meanwhile, are hailing the discovery as one of the most important in decades, particularly for issues surrounding the repatriation of human remains from Native American burials, which modern tribes dont want to see harmed.

Presented here are a few examples, exposing the truth about these stories.
