These highly 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 tight 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.

These are also highly energetic and will ionize atoms, transmute nuclei, and generate x-rays themselves.

Immer wenn ein Lebewesen stirbt, beginnt eine Stoppuhr zu laufen.

Die Wissenschaft kann diese Uhr ablesen und so das Alter eines Fundes ermitteln. Source unknown — possibly das Museum für Vor‑ und Frühgeschichte (the Museum for pre‑ and early history) in Berlin.

Radiometric Dating BBC - History - Archaeology - Carbon Dating Dating Exhibit How about carbon dating? A secondary cosmic ray neutron of sufficient energy striking a common nitrogen 14 nucleus can force it to eject a proton.C like they absorb other isotopes of carbon — through the respiration of carbon dioxide — and then use this carbon to produce sugars, fats, proteins, and vitamins.The isotopic distribution of potassium on the Earth is approximately 93% Ar nuclei that appeared as a result of radioactive decay would be trapped by the crystal structure and accumulate as the mineral aged.In a hypothetical mineral sample with an initial population of 64 Potassium-Argon dating techniques have been used to date minerals covering the entire span of geologic history from 10 thousand to 3 billion years old.As a first approximation one can assume this, but more accurate results must take into account fluctuations in the intensity of the cosmic rays entering the Earth's atmosphere.
