cosmogenic radionuclide
Definición
- Cosmogenic radionuclides are radionuclides generated by the nuclear reactions during the interaction between high-energy cosmic rays and stable nuclei from the atmosphere. One of the well-known cosmogenic radionuclides is carbon-14, which is generated by the reaction 14N(n,p)14C. The other isotopes generated are as follows: 3H, 7Be, 22Na. Most of cosmogenic radionuclides are products of (n,p), (p,n) and especially spallation reactions. These nuclear reactions are very fast and occur in a time comparable to the time of transit of an incident particle across the nucleus (~10-22 s). The very short interaction time allows for an interaction of a single nucleon only (in extreme cases). These reactions are known as direct nuclear reactions.
