In radiometric dating, the decaying matter is called the parent isotope and the stable outcome of the decay is called the daughter product.Since the half-life of carbon-14 is 5730 years, scientists can measure the age of a sample by determining how many times its original carbon-14 amount has been cut in half since the death of the organism.It was discovered that some chemical elements, notably uranium and thorium, are strongly radioactive.These elements occur naturally in nearly all rocks, and they account for the radioactivity you could observe with a Geiger counter.Certain natural phenomena or processes, such as Earth's year-long solar orbit, and the resulting annual climatic variations that govern the growth of tree rings, can be used as "natural clocks." If we can find and date a rock that we know has been around since the Earth formed, we can measure the age of the Earth.Can we find in rocks a natural clock that has been operating since they formed?

This constant length of time is called the Some common rocks are weakly radioactive.

As shown in the diagram above, the radioactive isotope carbon-14 originates in the Earth's atmosphere, is distributed among the living organisms on the surface, and ceases to replenish itself within an organism after that organism is dead.

This means that lifeless organic matter is effectively a closed system, since no carbon-14 enters the organism after death, an occurrence that would affect accurate measurements.

If there is too much daughter product(in this case nitrogen-14), age is hard to determine since the half-life does not make up a significant percentage of the material's age.

The range of practical use for carbon-14 dating is roughly a few hundred years to fifty thousand years.

Possible ways of distinguishing mixing lines from isochron lines are explored, including believability, concordance with the geological time scale or other radiometric dates, the presence or absence of mixing hyperbolae, and the believability of daughter and reference isotope homogenization.
