Radiocarbon dating services uk
We are home to one of a new generation of ultra-compact AMS instruments, a MICADAS accelerator mass spectrometer, designed and built at ETH, Zurich.
The MICADAS is a high-precision, high throughput instrument and is capable of determining radiocarbon dates on both traditional graphite targets and CO (via a gas interface system).
For radiocarbon dating to be reliable scientists need to make a number of vital assumptions.
Firstly, Dr Libby assumed that C14 decays at a constant rate.
c14 dating is a joke, and forms part of the scientism cartel and to challenge this cartel is to incur the wrath of new fangled shamanic science priests the length and breadth of the land.As with any radioactive particle it decays over time. Libby in 1948 at the University of Chicago, showed that C14, tested in his laboratory, decayed at the rate that, projected out, would cause half of its weight to be lost in 5568 years.Hence, the term ‘half-life’ was given to radioactive substances.The industrial revolution has belched hundreds of thousands of tons of carbon gases into the atmosphere increasing the C12 ratio and atomic weapons testing have increased neutron levels.Thirdly, the environment in which the artefact lies heavily impacts on the rate of decay.The radiocarbon method measures the rate of decay in the C14 of organic matter therefore estimating how long ago death occurred.Archaeologists can use this method to date bone, teeth, plants, seeds, burned food remains, coprolites, wood, and any artefact that contains organic materials such as an iron axe head (iron cannot be tested using C14) with a wooden handle or a bronze spear with a wooden shaft.These anomalies have driven archaeologists to question their earlier conclusions about archaeological sites and their respective civilizations founded on artefact dating.Many theories about societies and their cultures have been based solely on C14 dating results.The stable C12 and C13, and the unstable or radioactive Carbon 14. Only one C14 atom exists for every one trillion C12 atoms.Nitrogen atoms in the upper atmosphere are struck by cosmic radiation and create C14 atoms.
