Samples from the past 70,000 years made of wood, charcoal, peat, bone, antler or one of many other carbonates may be dated using this technique.
You probably have seen or read news stories about fascinating ancient artifacts.
At an archaeological dig, a piece of wooden tool is unearthed and the archaeologist finds it to be 5,000 years old.
A child mummy is found high in the Andes and the archaeologist says the child lived more than 2,000 years ago.
Radiocarbon dating involves determining the age of an ancient fossil or specimen by measuring its carbon-14 content.
C-14 Decay Profile Clicking on the "Show Movie" button below will bring up an animation that illustrates how a C-14 sample is processed and the calculations involved in arriving at a date.Since dinosaurs are thought to be over 65 million years old, the news is stunning - and more than some can tolerate.After the AOGS-AGU conference in Singapore, the abstract was removed from the conference website by two chairmen because they could not accept the findings.Radiocarbon, or Carbon-14, dating is probably one of the most widely used and best known absolute dating methods. Radiocarbon dating relies on a simple natural phenomenon. This allowed for the establishment of world-wide chronologies.In this article, we will examine the methods by which scientists use radioactivity to determine the age of objects, most notably carbon-14 dating.Carbon-14 dating is a way of determining the age of certain archeological artifacts of a biological origin up to about 50,000 years old.By examining the object's relation to layers of deposits in the area, and by comparing the object to others found at the site, archaeologists can estimate when the object arrived at the site.Though still heavily used, relative dating is now augmented by several modern dating techniques.As the Earth's upper atmosphere is bombarded by cosmic radiation, atmospheric nitrogen is broken down into an unstable isotope of carbon - carbon 14 (C-14).The unstable isotope is brought to Earth by atmospheric activity, such as storms, and becomes fixed in the biosphere.
