Example Sentences
Recent Examples on the Web Tritium, a second isotope of the same material, may be there as well. 
Kat Friedrich, Popular Mechanics, 13 Sep. 2022 This is called paleolimnology, where researchers take the mud out of the bottom of lakes and scan that sediment for an isotope, Nitrogen-15. Isabelle Ross, Anchorage Daily News, 21 July 2022 This isotope buildup is calibrated to temperature, but that calibration requires knowing ocean salinity and how much water is locked up in ice caps. Howard Lee, Ars Technica, 30 Aug. 2022 Together, the two produce an isotope called germanium 71. Caroline Delbert, Popular Mechanics, 11 July 2022 The isotope records suggested that the fish's annual growth, which would coincide with the peak availability of its prey in summer, hadn't yet been reached. Katie Hunt, CNN, 23 Feb. 2022 The team also discovered another cluster of outlying isotope compositions dated between 1648 and 1660, years that correspond to the Eighty Years’ War or the Dutch War of Independence, according to UPI. Nora Mcgreevy, Smithsonian Magazine, 16 Dec. 2021 The second is the oxygen isotope ratios themselves. John Timmer, Ars Technica, 11 Aug. 2022 Atom Computing creates spin qubits by using unique energy levels in the isotope Strontium-87. Paul Smith-goodson, Forbes, 2 June 2022 See More
