How many years have passed.

Will you please check your post. I'm have a problem with the "higher" part. I was under the impression that C 14 content DECREASED with time, not increased.
Sorry my mistake. 14/6c has a half life of 5600 years. An analysis of charcoal from a coal fire show 14c content is 25 per cent of living wood.
How many years have passed since the wood for the fire was was cut
