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.
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 ]
Other common rubidium compounds are the corrosive rubidium hydroxide (RbOH), the starting material for most rubidium-based chemical processes; rubidium carbonate (Rb 2 CO 3), used in some optical glasses, and rubidium copper sulfate, Rb 2 SO 4 ·CuSO 4 ·6H 2 O. Rubidium silver iodide (RbAg 4 I 5) has the highest room temperature conductivity ...
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 ...
Strontium-82 has a half-life of 25.5 days while Rubidium-82 has a half-life of 76 seconds. Heart muscles can take up Rubidium-82 efficiently through sodium–potassium pump. Compared with Technetium-99m, Rubidium-82 has higher uptake by the heart muscles. However, Rubidium-82 has lower uptake by heart muscles when compared to N-13 ammonia.
Rubidium Rb Rb + Potassium K K + Sodium Na Na + Lithium Li Li + Barium Ba Ba 2+ Strontium Sr Sr 2+ Calcium Ca Ca 2+ Magnesium Mg Mg 2+ reacts very slowly with cold water, but rapidly in boiling water, and very vigorously with acids: Beryllium Be Be 2+ reacts with acids and steam Aluminium Al Al 3+ Titanium Ti Ti 4+ reacts with concentrated ...
While the difficulty of obtaining macroscopic samples of synthetic elements in part explains their high value, there has been interest in converting base metals to gold (Chrysopoeia) since ancient times, but only deeper understanding of nuclear physics has allowed the actual production of a tiny amount of gold from other elements for research ...
