Carbon 14 radiometric dating method
So, the fossil is 8,680 years old, meaning the living organism died 8,680 years ago.
Love-hungry teenagers and archaeologists agree: dating is hard.
Radiocarbon dating can be used on samples of bone, cloth, wood and plant fibers.
The half-life of a radioactive isotope describes the amount of time that it takes half of the isotope in a sample to decay.
At an archaeological dig, a piece of wooden tool is unearthed and the archaeologist finds it to be 5,000 years old.
At any particular time all living organisms have approximately the same ratio of carbon 12 to carbon 14 in their tissues.How do scientists know how old an object or human remains are?What methods do they use and how do these methods work?After 5,730 years, the amount of carbon 14 left in the body is half of the original amount.If the amount of carbon 14 is halved every 5,730 years, it will not take very long to reach an amount that is too small to analyze.
