Scientists use isotopes to track the movement of water through the ecosystem.
Careers that involve carbon-14 include archaeology, paleontology, geology, and forensic science. These fields often use carbon-14 dating to determine the age of artifacts, fossils, or geological samples based on the decay of carbon-14 isotopes.
Scientists use the relative amount of stable and unstable isotopes in an object to determine its age.
All nuclear medicine techniques use radioactive isotopes.
Some careers that use the Spanish language include customer service and airline attendants.
electricians.
Some imaging uses radioactive isotopes to see various parts of the body.
Scientists use radiometric dating to determine the age of the Earth by measuring the decay of radioactive isotopes in rocks and minerals. By analyzing the ratio of parent isotopes to daughter isotopes, scientists can calculate the age of the Earth based on the rate of decay of these isotopes.
