Radiocarbon dating stuff works hub people dating
By measuring how much carbon-14 still remains in an organic compound, you can calculate how old it is.This method also works on some inorganic compounds, as long as they also assimilated carbon-14 during their formation.Libby confirmed the accuracy of radiocarbon dating by comparing his results with the known age of tree ring samples.
Carbon-14 is constantly being formed in the atmosphere as cosmic rays interact with nitrogen gas, and it gets absorbed by every living thing on Earth.
I have tried here to answer some of the frequently asked questions that I receive from students via email, as well as providing some basic information about scientific dating methods.
"Everything which has come down to us from heathendom is wrapped in a thick fog; it belongs to a space of time we cannot measure.
We know that it is older than Christendom, but whether by a couple of years or a couple of centuries, or even by more than a millenium, we can do no more than guess." [Rasmus Nyerup, (Danish antiquarian), 1802 (in Trigger, 19)].
The person who wrote these words lived in the 1800s, many years before archaeologists could accurately date materials from archaeological sites using scientific methods.
