It is founded on unprovable assumptions such as 1) there has been no contamination and 2) the decay rate has remained constant.We know that it is older than Christendom, but whether by a couple of years or a couple of centuries, or even by more than a millenium, we can do no more than guess." [Rasmus Nyerup, (Danish antiquarian), 1802 (in Trigger, 19)].The person who wrote these words lived in the 1800s, many years before archaeologists could accurately date materials from archaeological sites using scientific methods.The C14 method has been and continues to be applied and used in many, many different fields including hydrology, atmospheric science, oceanography, geology, palaeoclimatology, archaeology and biomedicine.

All plants and animals on Earth are made principally of carbon.

The radiocarbon method was developed by a team of scientists led by the late Professor Willard F.
