Beryllium10 Mass Spectrometry with a Cyclotron | Science

Abstract. The Grenoble cyclotron has been used as a mass spectrometer to measure ratios of beryllium10 to beryllium9 of 10 –8, 10 –9, and 10 –10 in standardized beryllium oxide samples. Similar measurements can be used to determine cosmogenic beryllium10 (halflife, x 10 6 years) profiles in various geophysical reservoirs such as sea sediments and polar ice.

Beryllium10 Wikipedia

Beryllium10 (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. [2] [3] [4] Beryllium10 has a halflife of × 10 6 years, [5] [6] and decays by beta decay to stable boron10 with a maximum energy of keV.

Beryllium 10 that is added to the sea may be scavenged by such particles, but as they settle out into deeper waters the organic matter may oxidize and calcareous organisms may slowly dissolve, releasing 10 Be back into solution, though fecal pellets may carry much of the 10 Be to the seafloor.

Beryllium 10 and climate | Watts Up With That?

Mar 17, 2009· Quick primer: Beryllium10 is an isotope that is a proxy for the sun’s activity. Be 10 is produced in the atmosphere by cosmic ray collisions with atoms of oxygen and nitrogen. Beryllium 10 concentrations are linked to cosmic ray intensity which can be a proxy for solar strength.
