A scientist who uses carbon 14 dating is measuring
The relative dating method worked very well, but only in sites which were had a connection to the relative scale. When radiocarbon dating was developed, it revolutionised archaeology, because it enabled them to more confidently date the past, and to build a more accurate picture of the human past.The archaeologist Colin Renfrew (1973) called it the development of this dating method 'the radiocarbon revolution' in describing its great impact upon the human sciences.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 radiocarbon method was developed by a team of scientists led by the late Professor Willard F.Libby of the University of Chicago after the end of World War 2.
In Nyerup's time, archaeologists could date the past only by using recorded histories, which in Europe were based mainly on the Egyptian calendar.Libby later received the Nobel Prize in Chemistry in 1960 for the radiocarbon discovery.Today, there are over 130 radiocarbon dating laboratories around the world producing radiocarbon dates for the scientific community.Welcome to the K12 section of the Radiocarbon WEBinfo site.The aim here is to provide clear, understandable information relating to radiocarbon dating for the benefit of K12 students, as well as lay people who are not requiring detailed information about the method of radiocarbon dating itself.
In the 1940s, scientists succeeded in finding out how long it takes for radiocarbon to disappear, or decay, from a sample of carbon from a dead plant or animal.
