Radiocarbon dating coal

Radioactive carbon (Carbon 14) is formed in the upper atmosphere as a byproduct of cosmic radiation.

But as the method was refined, it started to show rather regular anomalies.

First, it was noticed that, when radiocarbon dated, wood grown in the 20th century appears more ancient than wood grown in the 19th century.

The second is a set of new samples that the RATE team collected and sent to a leading radiocarbon AMS laboratory to be dated.

In both cases, I am convinced that the “intrinsic radiocarbon” is nothing more than contamination and instrument background.
