Rubidium-82 (82 Rb) is a radioactive isotope of rubidium. 82 Rb is widely used in myocardial perfusion imaging. This isotope undergoes rapid uptake by myocardiocytes, which makes it a valuable tool for identifying myocardial ischemia in Positron Emission Tomography (PET) imaging. 82 Rb is used in the pharmaceutical industry and is marketed as ...
Other than 87 Rb, the longest-lived radioisotopes are 83 Rb with a half-life of 86.2 days, 84 Rb with a half-life of 33.1 days, and 86 Rb with a half-life of 18.642 days. All other radioisotopes have half-lives less than a day. 82 Rb is used in some cardiac positron emission tomography scans to assess myocardial perfusion. It has a half-life of ...
[24] [25] Thirty additional rubidium isotopes have been synthesized with half-lives of less than 3 months; most are highly radioactive and have few uses. [26] Rubidium-87 has a half-life of 48.8 × 10 9 years, which is more than three times the age of the universe of (13.799 ± 0.021) × 10 9 years, [27] making it a primordial nuclide.

Rubidium-82 chloride is a form of rubidium chloride containing a radioactive isotope of rubidium. It is marketed under the brand name Cardiogen-82 by Bracco Diagnostics for use in Myocardial perfusion imaging . [ 1 ]
This is a list of radioactive nuclides (sometimes also called isotopes), ordered by half-life from shortest to longest, in seconds, minutes, hours, days and years. Current methods make it difficult to measure half-lives between approximately 10 −19 and 10 −10 seconds.

Niobium-95, with a half-life of 35 days, is initially present as a fission product. The only stable isotope of niobium has mass number 93, and fission products of mass 93 first decay to long-lived zirconium-93 (half-life 1.53 Ma). Niobium-95 will decay to molybdenum-95 which is stable.
