: of or relating to the measurement of geologic time by means of the rate of disintegration of radioactive elements
Example Sentences
Recent Examples on the Web Scientists, using radiometric dating, estimate the Earth itself is 4.5 billion years old. 
Isaac Skromne, The Conversation, 18 July 2022 The debris lodged into the fish's gills, called spherules, has been linked to the impact location in Mexico's Yucatan peninsula through radiometric dating, per the BBC. Elizabeth Gamillo, Smithsonian Magazine, 13 Apr. 2022 But Vidal and colleagues were able to determine the age of the eruption that deposited the ash by sampling rocks closer to their volcanic sources, in places where ashy debris contained plenty of larger crystals suitable for radiometric dating. Brian Handwerk, Smithsonian Magazine, 12 Jan. 2022 So having an absolute radiometric date for this surface helps us to calibrate the flux curve, which helps us to date other surfaces. David Bressan, Forbes, 10 Oct. 2021 This comparative approach, along with advances in radiometric dating methods, yielded a more refined sequence of events than previous studies. BostonGlobe.com, 21 June 2021 When examining remnants from the past, experts use radiometric dating, a versatile technique that involves counting radioactive atoms of certain elements that are still present in a sample.
