Cartoon illustrating cosmogenic nuclide exposure ages. A glacier transports an erratic boulder, and then recedes, exposing it to cosmic rays.Spallation reactions occur in minerals in the rocks upon bombardment by cosmic rays.When one of these particles strikes an atom it can dislodge one or more protons and/or neutrons from that atom, producing a different element or a different isotope of the original element.

By the time the cosmic ray cascade reaches the surface of Earth it is primarily composed of neutrons.Although dating with this method is expensive and the entire process takes a long time, TCN dating has the advantage that the dateable material is produced by the rockslide event itself by exposing fresh material surfaces to the cosmic rays.With the accuracy of modern instruments general every surface older than about 1000 years can be dated and the uncertainty limits today lie below 10% of the age.These particles interact with atoms in atmospheric gases (and thereby producing northern lights) and the surface of Earth.When one of these particles strikes an atom it can dislodge protons and/or neutrons from that atom, producing a different element or a different isotope of the original element.
