carbon 14 radioactive dating technique-85

The photograph shows the CEA ARTEMIS facility in Saclay (France).

ARTEMIS/CEA The measurement of carbon-14 activity requires to collect a sufficiently large of the fossil. There are a trillion times less (10 to the power -12) of carbon-14 radioactive than carbon-12.

Today, there are over 130 radiocarbon dating laboratories around the world producing radiocarbon assays for the scientific community.

The C14 technique has been and continues to be applied and used in many, many different fields including hydrology, atmospheric science, oceanography, geology, palaeoclimatology, archaeology and biomedicine.

It has been replaced since 2004 by Artemis, a mass spectrometer capable of dating each year 4,500 samples of less than a milligram.
