How is radioactive dating performed
Learn about half-life and how it is used in different dating methods, such as uranium-lead dating and radiocarbon dating, in this video lesson. As we age, our hair turns gray, our skin wrinkles and our gait slows.However, rocks and other objects in nature do not give off such obvious clues about how long they have been around.Plus, get practice tests, quizzes, and personalized coaching to help you succeed.Try it risk-free Radiometric dating is used to estimate the age of rocks and other objects based on the fixed decay rate of radioactive isotopes.But results can be gotten that are surprisingly accurate.
Carbon dating has the peculiar property that it works primarily on dead things.Another common technique in dating an object is carbon dating.Because the amount of carbon-14 has remained roughly constant through time on the earth it is possible to calculate the age of an object by finding the proportion of carbon-14 to carbon-12.The proportion of potassium to argon suggests how old the object in question is.
An equation used is t = (1/c)Ln(1 (D/P)) Where c is the decay constant D is number of daughter atoms (number decayed) P is the number of parent atoms (number undecayed) t is the age of the object.
No, radioactive dating does not produce exact results.
