The half-life of carbon-14 is 5730 years. A bone is discovered which has 20 percent of the carbon-14 found in the bones of other living animals. How old is the bone? The half-life of Carbon-14 is approximately 5,730 years. If an artifact that original...
Finally, C14 dating is not able to date very old fossils. It is often assumed that carbon dating can date anything. But with a 5600 year half life, anything over 45,000 years will only have 1/16th the concentration of C14 it had when the animal died. As concentrations decrease, the me...
