It starts by giving a brief explanation about radioactive atoms and isotopes. It also explains what cosmic rays are and how they interact with the atmosphere to form carbon-14. The carbon cycle and its radioactive decay allow determining historical and prehistoric dates in organic samples of carbon-14. Finally, the success of this method is shown by naming some famous examples of carbon-14 dating, such as the Chinchorro and Otzi mummies, among others.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Un Reloj Marcha Atr\u00e1s The talk aims to bring high school students closer to the use of carbon-14 as a mechanism for temporal dating of fossil remains.
