kosmogenisk
Kosmogenisk refers to substances, isotopes, or processes produced by cosmic rays interacting with matter, either in space or on Earth. The term is used in geology, astroparticle physics, and archaeology to describe materials whose isotopic composition records exposure to cosmic radiation. Cosmogenic nuclides can accumulate in surface rocks, ice, sediments, meteorites, and lunar samples, providing information about exposure histories, shielding, and space weather.
Production occurs mainly by spallation reactions when high-energy protons and heavier cosmic-ray particles strike target nuclei,
Applications include exposure dating of surfaces such as rock faces, glacial moraines, and ice cores; reconstruction
Measurement typically uses accelerator mass spectrometry to detect rare cosmogenic isotopes at trace levels. Production-rate calibrations
