What is the importance of carbon-14?

Answer 1

#""^14C# is a radioisotope of carbon with a half life of 5,730 years, and fairly negligible natural abundance.

Because it is radioisotope, and dead tissue does not absorb #""^14C#, it can be used to date archaeological specimens composed of dead tissue (from plant or animal matter) from up to 60,000 years ago.
