Twenty four isotopes of rubidium are known. Naturally occurring rubidium is made of two isotopes, 85Rb and 87Rb. Rubidium-87 is present to the extent of 27.85% in natural rubidium and is a beta emitter with a half-life of 4.9 x 10 10 years. Ordinary rubidium is sufficiently radioactive to expose a photographic film in about 30 to 60 days.

Rubidium chloride, rubidium hydroxide, and rubidium iodide are water soluble. These compounds have several established therapeutic applications. For example, rubidium chloride has been used as an antidepressant (O'Neil, 2006) and rubidium iodide has been used as an iodine source for the treatment of goiter (Wagner, 2011).
