[vi] How would a recent past of high volcanism, as shown by ancient lava fields, ash falls, and dead volcanoes, have affected ancient carbon isotope ratios?

Maybe one in a trillion carbon atoms are carbon-14.

Radiocarbon dating is a method of estimating the age of organic material.

It was developed right after World War II by Willard F.

To measure the amount of radiocarbon left in a artifact, scientists burn a small piece to convert it into carbon dioxide gas.

Radiation counters are used to detect the electrons given off by decaying Carbon-14 as it turns into nitrogen.

Search for carbon 14 and carbon dating:

So the method itself is not the issue—it’s the that are made when the raw isotope ratio gets converted to calendar years that carbon dating becomes unreliable and inaccurate, especially on very old artifacts.
