Carbon 14 dating reliability
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.
The C14 method has been and continues to be applied and used in many, many different fields including hydrology, atmospheric science, oceanography, geology, palaeoclimatology, archaeology and biomedicine.
All plants and animals on Earth are made principally of carbon.
Rasmus Nyerup's quote reminds us of the tremendous scientific advances which have taken place in the 20th century.
Animals eat plants, and some eat other animals in the food chain.
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 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.
