The use of carbon-14, also known as radiocarbon, to date organic materials has been an important method in both archaeology and geology.The technique was pioneered over fifty years ago by the physical chemist Willard Libby, who won the 1960 Nobel Prize for his work on C.Measuring the ratio of radioactive to stable carbon, we can estimate the age of carbon-bearing samples.

Theoretically, radiocarbon techniques have the ability to date samples to around 75,000 years, but the working threshold of reliable dating is around 50,000 years.

Samples significantly older than this have very little or even no measurable C left.

There are many laws that govern the peculiarities of everyday life, of which Murphy’s Law is the best known.

But in my engagement with those teetering within the creationism debate, I’ve discovered a new pattern of behavior that perhaps deserves its own name. Simply put, the longer one discusses the age of the Earth, the more likely a flawed statement about radiocarbon dating will steer the conversation into futility.

The unprocessed diamond samples probably reflect instrument background.

Coal and diamond samples have been measured by others down to instrument background levels, giving no evidence for intrinsic radiocarbon.I was looking at talk origins’ little archive on Diamonds and C14 in summary.They say Radioisotope evidence presents significant problems for the young earth position.It can combine with other atoms and molecules such as oxygen to create carbon dioxide, or CO2.Through the process of photosynthesis, plants absorb carbon dioxide which contains C left in a sample to accurately measure without contamination.The process of sample preparation and analysis depends on the technique (gas proportional counting, liquid scintillation, or accelerator mass spectrometry, for example), of which each has its own limitations and potential for error and uncertainty.
