Radiocarbon dating dates back
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.It is called 'radio'-carbon, because it is 'radioactive'.This means that its atomic structure is not stable and there is an uneasy relationship between the particles in the nucleus of the atom itself.The relative dating method worked very well, but only in sites which were had a connection to the relative scale. When radiocarbon dating was developed, it revolutionised archaeology, because it enabled them to more confidently date the past, and to build a more accurate picture of the human past.
A tiny part of the carbon on the Earth is called Carbon-14 (C14), or radiocarbon.
During the period of a plant's life, the plant is taking in carbon dioxide through photosynthesis, which is how the plant makes energy and grows.
Animals eat plants, and some eat other animals in the food chain.
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.
