The Bill & Melinda Gates Foundation is a Strategic Partner.more Radiocarbon dating has transformed our understanding of the past 50,000 years.

The number used to identify the isotope refers to the total number of particles in the nucleus of each atom.Radioactive decay allows geologists and physicists to measure the age of ancient fossils, rocks and even the Earth.This process is called radiometric or radioactive dating.Luckily, we can measure these fluctuations in samples that are dated by other methods.Tree rings can be counted and their radiocarbon content measured.

Radiometric dating is possible because the radioactive decay of large numbers of radioactive atoms follows a predictable pattern.
