For in carbon 14 dating
In addition, there are trace amounts of the unstable isotope carbon-14 (14C) on Earth.
Carbon-14 has a relatively short half-life of 5730 years, meaning that the amount of carbon-14 in a sample is halved over the course of 5730 years due to radioactive decay.
Carbon dating, also known as radiocarbon dating, is a method of estimating the age of carbon-bearing materials up to 60,000 years old.
Understand how decay and half life work to enable radiometric dating.A hydrocarbon found in beach sediments, for example, might derive from an oil spill or from waxes produced by plants.Carbon 14 is a common form of carbon which decays exponentially over time.All carbon atoms have a nucleus containing six protons.Ninety-nine percent of these also contain six neutrons.
Following a conference at the University of Cambridge in 1962, a more accurate figure of 5730 years was agreed upon and this figure is now known as the Cambridge half-life.
