Radioactive isotope used for age dating


The object's approximate age can then be figured out using the known rate of decay of the isotope.Radiocarbon dating is one kind of radiometric dating, used for determining the age of organic remains that are less than 50,000 years old.Continue Reading The key to an age of a substance is the decay-product ratio.The ratio of the original isotope and its decay product determines how many half-lives have occurred since the sample formed.Learn about different types of radiometric dating, such as carbon dating.



For example, say a fossil is found that has 35% carbon 14 compared to the living sample. We can use a formula for carbon 14 dating to find the answer.Where t is the age of the fossil (or the date of death) and ln() is the natural logarithm function.If the fossil has 35% of its carbon 14 still, then we can substitute values into our equation.A method for determining the age of an object based on the concentration of a particular radioactive isotope contained within it.
