Facts about carbon dating

One of the mindblowing uses of radioactivity, carbon dating is based on decay rate of carbon’s radioactive isotope C-14 that is absorbed by all the living organisms while alive.

Once they die, no additional C-14 gets accumulated and all the C-14 amount already present decays to N-14 making radioactive emissions.

And this revolutionary method of radiocarbon dating or C-14 dating was used by several scientists for estimation of age of ancient artifacts.

They found that it was accurate for samples older only upto 70,000 years as the objects older than this contained way too little C-14 for detection.

Intrigued by the properties of radiocarbon C-14 (the radioactive isotope of carbon), Libby pioneered the method of radiocarbon dating.

Here are some interesting facts about carbon dating to note.

In the end of 1940s, Willard Libby developed the method of carbon dating.

The scientists improved their equipments for detection of these elements.

In 1939, the cyclotron particle accelerator was used as a mass spectrometer which helped in dating samples as old as 100,000 years.
