Learn about half-life and how it can be used to radiometrically date fossils using radioactive what is half-life scale is by using radiometric dating. Useful for calculating today's activity for any radioactive isotope you may also back decay sources to find out the original activity (or for any date), knowing the current activity. Methods of dating the age of meteorites meteorites are among the oldest objects we know about - formed about 45 billion years ago the only suitable clocks we have found involve the. Radiometric dating works by measuring how much a radioactive material has decayed, and using its known decay rate to calculate when the material was solidified there are a variety of ways.
How science figured out the age of earth for centuries scholars sought to determine earth’s age, russell, author of the 1921 article on radioactive dating,. The stable form of carbon is carbon 12 and the radioactive isotope carbon 14 decays over time which means that carbon 14 dating is not particularly helpful for.
