Geologic Age Dating Explained - Kids Discover These hy energetic nuclear bullets wreak havoc on the atoms in the upper atmosphere: tearing electrons from their orbitals and setting them free, knocking neutrons and protons from the tht confines of the nucleus and setting them free, generating x-rays and gamma rays as they decelerate, and creating exotic particles like muons and pions directly from their excessive kinetic energy. So carbon 14 is used to date materials that aren't that old geologiy, say in the tens of thousands of years, while potassium-argon dating can.
