Radiocarbon dating is a method that provides objective age estimates for carbon-based materials that originated from living organisms. The impact of the radiocarbon dating technique on modern man has made it one of the most significant discoveries of the 20th century. Archaeology and other human sciences use radiocarbon dating to prove or disprove theories. Over the years, carbon 14 dating has also found applications in geology, hydrology, geophysics, atmospheric science, oceanography, paleoclimatology and even biomedicine.
What is Carbon (14C) Dating? Carbon Dating Definition
Radioactive material gets a bad rap, what with radiation and fallout and nuclear waste and all. But it offers some practical uses. One of the coolest OK, maybe the coolest is using radioactive carbon to determine the age of old bones or plants. To understand this, you must first understand radioactivity and decay. When an element undergoes radioactive decay, it creates radiation and turns into some other element. Of course, the best way to understand something is to model it, because the last thing you want to do at home is experiment with something radioactive. Here are two ways to model radioactive decay.
How does carbon 14 decay?
In this section we will explore the use of carbon dating to determine the age of fossil remains. Carbon is a key element in biologically important molecules. During the lifetime of an organism, carbon is brought into the cell from the environment in the form of either carbon dioxide or carbon-based food molecules such as glucose; then used to build biologically important molecules such as sugars, proteins, fats, and nucleic acids. These molecules are subsequently incorporated into the cells and tissues that make up living things.
