(Today, based on refined calculations/techniques the half-life rate of carbon-14 is generally considered to be 5,730 years) (Wheatley 20; De Young 20). Essay Carbon 14 Dating and over other 26,000 free term papers, essays and research papers examples are available on the website!Willard discovered this decay rate and studied it until he was able to use it to determine the age of plant-based artifacts.Geologists, archeologists, anthropologists and other scientists have utilized his discovery extensively to date their own discoveries and in the past, Carbon-14 has been used to determine the age of mummies and prehistoric artifacts such as fossils.Libby in the late 1940s, has significantly improved the accuracy of assigning dates to past events and artifacts as far back as 70,000 years.It is helping archaeologists, geologists, and anthropologists reconstruct the world’s history by filling in some of the many blank dates in the chronology of the history of our human world and by substantiating and revising other dates.
Utilizing this discovery of the unstable radioactive isotope of carbon, Libby formulated an idea for using the decay rate of this radioactive form of carbon to date the remains of once-living plants and animals such as charcoal, wood, bone, shells, and fossils.
In 1948, while at the University of Chicago, he and his colleagues started experimenting with carbon-14 as a means for dating the past.
The scientists proved that carbon-14, which is present in our atmosphere as carbon dioxide, is absorbed by plants, animals, and human beings at a constant rate, and that the amount of carbon-14 is stabilized at a specific amount.
Radiocarbon dating, also known as carbon-14 dating, has been one of the most important radioisotope dating methods used.
This scientific tool, which was first developed by Willard F.
A living organism can only intake a finite amount of carbon-14.
