Half life period of $C^{14}$ is : -Carbon-14 is a radioactive isotope of carbon that decays by $\beta$-emission to nitrogen-14.
Its half life is about 5730 years (often rounded to about 5000 years).
It is used in radiocarbon dating of fossils and archaeological remains up to about 50,000 years old.
So the half life of $C^{14}$ is about 5000 years.
