Beryllium-10 (10Be) is a

galactic cosmic ray particles. The spallation
of the reaction products is the source of 10Be (t, u particles like n or p):

14N(t,5u)10Be; Example: 14N(n,p α)10Be
16O(t,7u)10Be
Plot showing variations in solar activity, including variation in 10Be concentration which varies inversely with solar activity. (Note that the beryllium scale is inverted, so increases on this scale indicate lower beryllium-10 levels).

Because beryllium tends to exist in

alkaline, beryllium drops out of solution. Cosmogenic 10Be thereby accumulates at the soil surface, where its relatively long half-life (1.387 million years) permits a long residence time before decaying to 10B
.

10Be and its daughter product have been used to examine

proxy data measure for cosmogenic nuclides to characterize solar and extra-solar attributes of the past from terrestrial samples.[9]
