Radiometric dating, or radioactive dating as it is sometimes called, is a method used to date rocks and other objects based on the known decay rate of radioactive isotopes. Different methods of radiometric dating can be used to estimate the age of a variety of natural and even man-made materials.Click to see full answer. Keeping this in view, what is the purpose of radioactive dating?Radioactive dating enables geologists to record the history of the earth and its events, such as the dinosaur era, within what they call the geologic time scale. Radioactive dating uses the ratios of isotopes and their specific decay products to determine the ages of rocks, fossils, and other substances.Subsequently, question is, what is radioactive dating answers? Radioactive dating refers to the process of measuring the age of an object using the amount of a given radioactive material it contains. Relative dating, meanwhile, measures the order of past events, without determining their absolute age. what isotopes are used for radioactive dating? Isotopes Half-life (years) Uranium-235 Lead-207 704 million Rubidium-87 Strontium-87 48.8 billion Potassium-40 Argon-40 1.277 billion Carbon-14 Nitrogen-14 5730 ± 40 Are all elements useful for radioactive dating?Many different radioactive isotopes and techniques are used for dating. For an element to be useful for geochronology (measuring geological time), the isotope must be reasonably abundant and produce daughter isotopes at a good rate. Either a whole rock or a single mineral grain can be dated.
