Carbon dating world history
They used pottery and other materials in sites to date 'relatively'.
They thought that sites which had the same kinds of pots and tools would be the same age.
Welcome to the K12 section of the Radiocarbon WEBinfo site.
The aim here is to provide clear, understandable information relating to radiocarbon dating for the benefit of K12 students, as well as lay people who are not requiring detailed information about the method of radiocarbon dating itself.
The job of a radiocarbon laboratory is to measure the remaining amounts of radiocarbon in a carbon sample.
This is very difficult and requires a lot of careful work to produce reliable dates.
Libby found that it took 5568 years for half the radiocarbon to decay.After twice that time (about 11000 years), another half of that remaining amount will have disappeared.After another 5568 years, again another half will have disappeared.Because carbon is very common on Earth, there are alot of different types of material which can be dated by scientists.Below is a list of the different kinds of materials which can be dated: Libby tested the new radiocarbon method on carbon samples from prehistoric Egypt whose age was known.
Rasmus Nyerup's quote reminds us of the tremendous scientific advances which have taken place in the 20th century.
