Carbon 14 dating test

You can work out that after about 50 000 years of time, all the radiocarbon will have gone.Therefore, radiocarbon dating is not able to date anything older than 60 or 70 000 years old.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.

Libby later received the Nobel Prize in Chemistry in 1960 for the radiocarbon discovery.Today, there are over 130 radiocarbon dating laboratories around the world producing radiocarbon dates for the scientific community.After the war he became very interested in peaceful applications of atomic science.He and two students first measured the "half-life" of radiocarbon.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.

The archaeologist Colin Renfrew (1973) called it the development of this dating method 'the radiocarbon revolution' in describing its great impact upon the human sciences.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 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.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.
