Hey! I am Varsha. As my mother stopped writing blogs. I am going to continue her blog. Hope you all like it😊.
So have you ever wondered how archaeologists tell the dates of fossils that they have found? They use dating techniques. Now I am going to tell about one of them called RADIOCARBON DATING

Carbon 14 is an isotope of carbon. It is weakly radioactive and is present in our body too in a very low ratio.
In this technique, the sample is dropped in a chemical to remove all other contamination except for carbon and carbon 14. Then it is sent through an ACCELERATOR MASS SPECTROMETER (refer pic below) so it can measure the amount of carbon 14 in an organism. This is done because after death carbon 14 diminishes at a certain rate. Using this measurement we can calculate the year when that organism was alive.
ISOTOPE: It is an unstable atom and it produces radiation to be stable.
