rubidium rb isotopes

Rubidium 87 Chloride (Rubidium-87) is a stable (non-radioactive) isotope of Rubidium. It is both naturally occurring and produced by fission. Rubidium 87 Chloride is one of over 250 stable isotopes produced by American Elements for biological and biomedical labeling, as target materials and other applications. Rubidium Chloride is generally immediately available in most volumes.

Isotopes: There are 29 known isotopes of rubidium. Natural rubidium consists of two isotopes, rubidium-85 (stable with 72.15% abundance) and rubidium-87 (27.85% abundance, a beta emitter with a half-life of 4.9 x 10 10 years). Thus, natural rubidium is radioactive, with sufficient activity to expose photographic film within 110 days.
