Reliability of radiocarbon dating

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.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.After twice that time (about 11000 years), another half of that remaining amount will have disappeared.

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.

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.
