Archaeology and radiocarbon dating
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.
However, experimental evidence indicates that C14 decay is slowing down and that millennia ago it decayed much faster than is observed today.
Nitrogen atoms in the upper atmosphere are struck by cosmic radiation and create C14 atoms.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.For example, C14 leaches at an accelerated rate from organic material saturated in water, especially saline water.Fourthly, for C14 to test accurately the artefact must have been protected from contamination.
