Beryllium-7 is an isotope with a half-life of 53.3 days that is generated naturally as a cosmogenic nuclide. [4] . The rate at which the short-lived 7. decay in the Sun is one of the sources of solar neutrinos, and the first type ever detected using the Homestake experiment. Presence of 7. [6]

The very short-lived beryllium isotope with a mass of 7, with a half-life of approximately 53 days, only occurs on Earth in very small traces, namely as an atmospheric spallation product of oxygen and nitrogen due to the action of cosmic radiation.

In recent years, beryllium-7 (Be-7, a radionuclide with half-life of 53.22 days) has received increased attention for its potential to trace sediments over timescales relevant to a single event, enabling an event-based partitioning of erosion into its components.

Beryllium-7（Be-7）是一种放射性同位素，其核中有4个质子和3个中子。 它具有半衰期较短的特点，约为53.12天。 其高能核发射特性，它常被用于放射性同位素标记和放射性示踪技术。

2022年5月1日 · Beryllium-7 (Be-7), with a decay half-life of around 53 days, is a cosmogenic gamma-emitting radionuclide generated in the upper atmosphere when secondary particles of cosmic-ray interact with the nuclei of nitrogen and oxygen atoms in the lower stratosphere and upper troposphere (Cruikshank et al., 1956; Lal and Peters, 1967). The production ...
