Question: What was the half life of carbon 14?

The half-life of radiocarbon (14C) is 5700 ± 30 yr, which makes it particularly useful for dating in archaeology.

What is the half-life of carbon-14 in standard form?

The half-life for 14C is approximately 5700 years, therefore the 14C isotope is only useful for dating fossils up to about 50,000 years old. Fossils older than 50,000 years may have an undetectable amount of 14C.
