Half life dating rocks

The half-life refers to the amount of time it takes for half the radiocarbon in a sample of bone or shell or any carbon sample to disappear.Libby found that it took 5568 years for half the radiocarbon to decay.Eventually, a particle is emitted from the carbon 14 atom, and carbon 14 disappears.Most of the carbon on Earth exists in a slightly different atomic form, although it is chemically speaking, identical to all carbon.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.

A tiny part of the carbon on the Earth is called Carbon-14 (C14), or radiocarbon.

Rasmus Nyerup's quote reminds us of the tremendous scientific advances which have taken place in the 20th century.

In Nyerup's time, archaeologists could date the past only by using recorded histories, which in Europe were based mainly on the Egyptian calendar.

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.
