Question: How old can an object be with carbon dating?

Geologists do not use carbon-based radiometric dating to determine the age of rocks. Carbon dating only works for objects that are younger than about 50,000 years, and most rocks of interest are older than that.

What is the time limit you can carbon-14 date an object?

Because the half-life of carbon-14 is 5,700 years, it is only reliable for dating objects up to about 60,000 years old.

What is the half-life of C 14?

5,730 years The time it takes for 14C to radioactively decay is described by its half-life. C has a half-life of 5,730 years.
