Credible carbon dating

Radiocarbon dating is not affected seriously yet, they claim, but will be by 2020 if emissions continue.

Incidentally, lab techs already have to correct for another historical contingency: The fraction of carbon-14 in the atmosphere decreased after the Industrial Revolution with the rise of fossil fuel combustion.

When isotopes are to be designated specifically, the chemical symbol is expanded to identify the mass (for example, C is not stable.

As a result it is always undergoing natural radioactive decay while the abundances of the other isotopes are unchanged.

Your T-shirt could soon contain the same carbon-14 as William the Conqueror’s robe from 1066 AD, scientists warn.

Scientists place great faith in this dating method, and yet more than 50% of radiocarbon dates from geological and archaeological samples of northeastern North America have been deemed unacceptable after investigation.

While there is no proof that the rates were different in the past than they are today, there is also no proof that they were the same.

Objects have been carbon-dated and the results were within weeks of the known date of origin; the error values of experimentation were far greater than the actual difference between dated and known its body stops taking in carbon.
