Isotopes of beryllium - Wikipedia
Beryllium (4 Be) has 11 known isotopes and 3 known isomers, but only one of these isotopes (9 Be) is stable and a primordial nuclide. As such, beryllium is considered a monoisotopic element.
Beryllium Isotopes - List and Properties - ChemLin
List, data and properties of all known isotopes of Beryllium. 12 isotopes or nuclides of the element beryllium are known, of which only one - 9 Be - is stable. This makes beryllium a pure element and the only monoisotopic chemical element with an even number of protons in the nucleus. The atomic mass of beryllium is 9.0121831 (5) u.
Radioactive Decay and Half-Life Beryllium Isotopes - ThoughtCo
2020年2月28日 · This table lists the known isotopes of beryllium, their half-life, and type of radioactive decay. The first entry corresponds to the nucleus where j=0 or the most stable isotope. Isotopes with multiple decay schemes are represented by a range of half-life values between the shortest and longest half-life for that type of decay.

Beryllium has but a single isotope, beryllium-9 which is not radioactive but beryllium-10, which cosmic rays produce in the upper atmosphere, is radioactive with a half-life of 1.5 million years.
Beryllium Isotopes - SpringerLink
2017年9月13日 · Beryllium (atomic number 4) has twelve isotopes, but only three are routinely measured: 7 Be, 9 Be, and 10 Be. 9 Be is a stable isotope that is found naturally in geological materials typically at μg g −1 levels and is considered in the Beryllium chapter.

Beryllium - Wikipedia
The single primordial beryllium isotope 9 Be also undergoes a (n,2n) neutron reaction with neutron energies over about 1.9 MeV, to produce 8 Be, which almost immediately breaks into two alpha particles. Thus, for high-energy neutrons, beryllium is a neutron multiplier, releasing more neutrons than it absorbs.
