Reliability of carbon 14 dating
In the following article, some of the most common misunderstandings regarding radiocarbon dating are addressed, and corrective, up-to-date scientific creationist thought is provided where appropriate. Radiocarbon is used to date the age of rocks, which enables scientists to date the age of the earth.
Radiocarbon is not used to date the age of rocks or to determine the age of the earth.
For this reason special precautions need to be exercised when sampling materials which contain only small amounts of radiocarbon.
Reports of young radiocarbon ages for coal probably all stem from a misunderstanding of one or both of these two factors.
It is not difficult to see how such a claim could arise, however.
There are two characteristics of the instrumental measurement of radiocarbon which, if the lay observer is unaware, could easily lead to such an idea.
This gives the clam shell an artificially old radiocarbon age.
Of course, the table, so constructed, will only give the correct calibration if the tree-ring chronology which was used to construct it had placed each ring in the true calendar year in which it grew.
In the early days of radiocarbon analysis this limit was often around 20,000 radiocarbon years.
