For radiocarbon dating to be reliable scientists need to make a number of vital assumptions.
Firstly, Dr Libby assumed that C14 decays at a constant rate.
Radiocarbon or C14 dating employs complex systems of measuring the unstable isotopes in once living matter.
There are three forms of carbon that naturally occur forming the building blocks of all plant and animal life.
The unreliability of carbon 14 date testing is a great concern to honest archaeologists.
They get particularly concerned when C14 testing shows obviously inaccurate results and they are left in uncertainty about the reliability of the dates that they have previously never questioned.
The honest archaeologist can no longer propose theories and ideas without bringing a wider plate of evidences to the history table. If #2 is a Yes, how deep can radiation pass through ground?
Hi there, I was hoping you could answer a few questions. Thank you very much for taking the time to answer my questions!
Hence, the term ‘half-life’ was given to radioactive substances."Dr Libby assumed that C14 decays at a constant rate.However, experimental evidence indicates that C14 decay is slowing down and that millennia ago it decayed much faster than is observed today." I would be very interested in examining this experimental evidence.However its application has caused extreme confusion and misunderstanding of the archaeological record.Knowing the limitations of this dating method can help avoid colossal archaeological misinterpretations that would otherwise distort history.
The industrial revolution has belched hundreds of thousands of tons of carbon gases into the atmosphere increasing the C12 ratio and atomic weapons testing have increased neutron levels.
