· Cardiogen82 (rubidium Rb 82 generator) is a closed system used to produce rubidium Rb 82 chloride injection for intravenous administration. Rubidium Rb 82 chloride injection is indied for Positron Emission Tomography (PET) imaging of the myocardium under rest or pharmacologic stress conditions to evaluate regional myocardial perfusion in adult patients with suspected or existing .
Rubidium is a very soft, silverywhite metallic element. Its atomic number is 37 and its symbol is Rb. Rubidium was discovered in 1861 by the German chemists, Robert Bunsen and Gustav Kirchhoff. It is the 16th most abundant element in the Earth's crust (making rubidium a pretty common element).

Rubidium Rb 82 is a radioactive drug and should be handled with appropriate safety measures to minimize radiation exposure during administration [see Warnings and Precautions (]). Use waterproof gloves and effective shielding when handling rubidium Rb 82 chloride injection and
Rubidium Rb 82 chloride injection is a radioactive diagnostic agent indied for Positron Emission Tomography (PET) imaging of the myocardium under rest or pharmacologic stress conditions to evaluate regional myocardial perfusion in adult patients with suspected or existing coronary artery disease.
Rubidium82( Rb82) Rubidium82 is a positron emitting radiotracer with a physical halflife of 75 seconds. It is administered into the human body intravenously. Following intravenous administration, Rb82 is an analog to potassium and rapidly taken up by heart muscle.
37 Rb (Rubidium) Flashcard of Rubidium. Rubidium is a soft, silverywhite metallic, and one of the most electropositive element. It can be liquid at ambient temperature, but only on a hot day given that its melting point is about 40°C. It ignites spontaneously in air and reacts violently in water, setting fire to the liberated hydrogen.

Main Isotopes of Rubidium. Rubidium occurs in 2 natural isotopes: 85 Rb and 87 Rb. Of these, 87 Rb is very slightly radioactive, decaying by beta decay with a halflife of ×10 10 years. 85 Rb is the most common isotope, having a natural abundance of approximately 72%. Rubidium85 is composed of 37 protons, 48 neutrons, and 37 electrons.
· An atom of Rubidium in the gas phase, for example, gives off energy when it gains an electron to form an ion of Rubidium. Rb + e – → Rb – – ∆H = Affinity = kJ/mol. To use electron affinities properly, it is essential to keep track of sign. When an electron is added to a neutral atom, energy is released.
