What methods do they use and how do these methods work?

In this article, we will examine the methods by which scientists use radioactivity to determine the age of objects, most notably carbon-14 dating.

Carbon-14 dating is a radiometric dating technique used to deduce the approximate age of organic remains by measuring the quantity of C-14 isotopes in the sample and comparing them with current atmospheric levels.

C-12 and C-14 are two different isotopes of carbon.

Plants and animals absorb both C-12 and C-14 in the course of their natural lifetimes simply by carrying out these basic functions.

When they die, they cease to consume them, and the isotope of C-14 begins to revert back to its Nitrogen state at an exponential rate due to its radioactive decay.

Through the life of the organism, the proportion of C-14 to C-12 reaches the same proportion as in the rest of the environment.

When the organism dies, however, it ceases to incorporate carbon into its body.C-12 is stable, meaning it does not decay into other elements over time. It is formed when cosmic radiation strikes N-14 (Nitrogen), converting it into C-14, and it decays back into N-14, with a half-life of 5730 years, meaning that for any sample of C-14, half of it will decay back into N-14 every 5730 years.Carbon-14 is used to date dead plants and animals, because plants and animals incorporate C-14 into their bodies by eating, drinking, and breathing in an environment containing C-14.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.This property makes it especially useful in a process known as “radiocarbon dating”, or carbon dating for short.
