Beryllium-10 - Wikipedia

Beryllium-10 (10 Be) is a radioactive isotope of beryllium.It is formed in the Earth's atmosphere mainly by cosmic ray spallation of nitrogen and oxygen. Beryllium-10 has a half-life of 1.39 × 10 6 years, and decays by beta decay to stable boron-10 with a maximum energy of 556.2 keV. It decays through the reaction 10 Be→ 10 B + e −.Light elements in the atmosphere react with high energy ...
