Definition of Cosmogenic. Meaning of Cosmogenic. Synonyms of Cosmogenic

- Cosmogenic nuclides (or cosmogenic isotopes) are rare nuclides (isotopes) created when a high-energy cosmic ray interacts with the nucleus of an in situ...
- between 103 and 106 years. The most common of these dating techniques is cosmogenic radionuclide dating. Earth is constantly bombarded with primary cosmic...
- three categories: primordial radionuclides, secondary radionuclides, and cosmogenic radionuclides. Radionuclides are produced in stellar nucleosynthesis and...
- directly with cosmic rays. The latter, if non-primordial, are called cosmogenic nuclides. Other types of natural nuclear reactions produce nuclides that...
- A Miyake event is an observed sharp enhancement of the production of cosmogenic isotopes by cosmic rays. It can be marked by a spike in the concentration...
- beryllium, and boron—as well as the isotope helium-3. This process (cosmogenic nucleosynthesis) was discovered somewhat by accident during the 1970s:...
- can affect the cosmogenic exposure dating of boulders by altering the cosmogenic isotope concentration. So, by finding the cosmogenic exposure for two...
- precipitation quickly becomes more alkaline, beryllium drops out of solution. Cosmogenic 10Be thereby ac****ulates at the soil surface, where its relatively long...
- isotopic analysis of exposed terrestrial rocks has demonstrated the cosmogenic (cosmic ray) production of 21Ne. This isotope is generated by spallation...
- (fast neutron reactors) and all nuclear weapons rely on fast neutrons. Cosmogenic neutrons are produced from cosmic radiation in the Earth's atmosphere...
