Limitations carbon 14 dating objects

Jump down to summary if you just want to know what both categories of limitations are.

The limitations of radiometric dating can be split into two general categories, analytical limitations and natural limitations.

Both Carbon-12 and Carbon-13 are stable, but Carbon-14 decays by very weak beta decay to nitrogen-14 with a half-life of approximately 5,730 years.

After the organism dies it stops taking in new carbon.

So you can never have perfect running conditions and certain parameters will change over time, this is just the nature of high-tech machinery.

The ratio of carbon-12 to carbon-14 is the same in all living things.

However, at the moment of death, the amount of carbon-14 begins to decrease because it is unstable, while the amount of carbon-12 remains constant in the sample.

Half of the carbon-14 degrades every 5,730 years as indicated by its half-life.

As you learned in the previous page, carbon dating uses the half-life of Carbon-14 to find the approximate age of certain objects that are 40,000 years old or younger.

In the following section we are going to go more in-depth about carbon dating in order to help you get a better understanding of how it works.
