Carbon dating method reliable
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.After twice that time (about 11000 years), another half of that remaining amount will have disappeared.
He and two students first measured the "half-life" of radiocarbon.
The radiocarbon method was developed by a team of scientists led by the late Professor Willard F.
Libby of the University of Chicago after the end of World War 2.
In the 1940s, scientists succeeded in finding out how long it takes for radiocarbon to disappear, or decay, from a sample of carbon from a dead plant or animal.
Willard Libby, the principal scientist, had worked in the team making the nuclear bomb during World War 2, so he was an expert in nuclear and atomic chemistry.
