beryllium isotopes variations

Isotopes of beryllium - Wikipedia

Beryllium (4Be) has 11 known isotopes and 3 known isomers, but only one of these isotopes ( Be ) is stable and a primordial nuclide. As such, beryllium is considered a monoisotopic element. It is also a mononuclidic element, because its other isotopes have such short half-lives that none are primordial and their abundance is very low (standard atomic weightis 9.0122). Beryllium is unique as being the only monoisotopic element with both an even number of protons and an odd number of neutrons. There are

Atmospheric impact on beryllium isotopes as solar activity proxy

frequent and large input of beryllium intrusions will have higher isotopes average values than other years and thus also a higher noise level in the whole dataset. This effect may not be catastrophic when fitting the production (ap-proximation of solar activity) to a long-term beryllium isotope time series (Figure 2). However, if several years

2019. 11. 15.  While several radiogenic isotope systems (e.g. Nd, Pb, Os) in the authigenic component of marine sediments show temporal patterns that could be interpreted in terms of fluctuations in chemical weathering rate over glacial cycles, recent work using beryllium isotopes suggests little such variation.

Beryllium 10 and climate – Watts Up With That?

2009. 3. 18.  Quick primer: Beryllium-10 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. One way to capture earth’s record of that proxy data is to drill deep ice cores.
