It is believed to be accurate for objects with a biological origin dating to up to 50,000 years old.
All living things contain a mixture of carbon 14 and carbon 12 atoms, with the ratio between the two remaining close to constant.
“If we determine the 13C value of the sample as well as using the radiocarbon method, we can find out whether the age is trustworthy.
That’s because the 13C value tells us whether the carbon of the sample has been affected by fossil carbon dioxide,” he said in a press release from the Alfred Wegener Institute.
As the carbon 14 decays the ratio between it and carbon 12 starts to change, because the amount of carbon 12 remains constant.
As scientists know the half life of carbon 14 (5,700 years), they can work out the age of any dead organism by comparing the ratio of carbon 12 to carbon 14 in it with the ratio in a living thing.
In all of the scenarios, he found that any distortions in the dating method could be detected and calculated with the 13C Suess effect.
