The decay of Rubidium-82, which undergoes positron emission.. Rubidium-82 is produced by electron capture of its parent nucleus, strontium-82.The generator contains accelerator produced 82 Sr adsorbed on stannic oxide in a lead-shielded column and provides a means for obtaining sterile nonpyrogenic solutions of rubidium chloride (halide salt form capable of injection).
Rubidium is a chemical element; it has symbol Rb and atomic number 37. It is a very soft, whitish-grey solid in the alkali metal group, similar to potassium and caesium. [9] Rubidium is the first alkali metal in the group to have a density higher than water.
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 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 ...
However, Rubidium-82 has lower uptake by heart muscles when compared to N-13 ammonia. But the positron energy emitted by Rubidium-82 is higher than N-13 ammonia and Fluorodeoxyglucose (18F) . On the other hand, the positron range (the distance travelled by a positron from its production site until its annihilation with an electron) is longer ...
Fission product yields by mass for thermal neutron fission of U-235 and Pu-239 (the two typical of current nuclear power reactors) and U-233 (used in the thorium cycle). This page discusses each of the main elements in the mixture of fission products produced by nuclear fission of the common nuclear fuels uranium and plutonium.
The energy emitted depends on the isotope that is decaying; the figure of 0.96 MeV applies only to the decay of carbon-11. The short-lived positron emitting isotopes 11 C (T 1 ⁄ 2 = 20.4 min ), 13 N (T 1 ⁄ 2 = 10 min ), 15 O (T 1 ⁄ 2 = 2 min ), and 18 F (T 1 ⁄ 2 = 110 min ) used for positron emission tomography are typically produced by ...
