Forty radioisotopes have been characterized, with the most stable, besides 176 Lu, being 174 Lu with a half-life of 3.31 years, and 173 Lu with a half-life of 1.37 years. All of the remaining radioactive isotopes have half-lives that are less than 9 days, and the majority of these have half-lives that are less than half an hour.
Lutetium salts are then selectively washed out by suitable complexing agent. Lutetium metal is then obtained by reduction of anhydrous LuCl 3 or LuF 3 by either an alkali metal or alkaline earth metal. [22] 2 LuCl 3 + 3 Ca → 2 Lu + 3 CaCl 2. 177 Lu is produced by neutron activation of 176 Lu or by indirectly by neutron activation of 176 Yb ...
Lutetium (177 Lu) oxodotreotide or 177 Lu dotatate, brand name Lutathera, is a chelated complex of a radioisotope of the element lutetium with dotatate, used in peptide receptor radionuclide therapy. Specifically, it is used in the treatment of cancers which express somatostatin receptors. [5] It is a radiolabeled somatostatin analog. [3] [6] [7]
Lutetium (177 Lu) chloride is a radioactive compound used for the radiolabeling of pharmaceutical molecules, aimed either as an anti-cancer therapy or for scintigraphy (medical imaging). [ 5 ] [ 6 ] It is an isotopomer of lutetium(III) chloride containing the radioisotope 177 Lu , which beta decays with a half-life of 6.64 days.
Lutetium (177 Lu) vipivotide tetraxetan, sold under the brand name Pluvicto, is a radiopharmaceutical medication used for the treatment of prostate-specific membrane antigen (PSMA)-positive metastatic castration-resistant prostate cancer (mCRPC). [5] [6] Lutetium (177 Lu) vipivotide tetraxetan is a targeted radioligand therapy. [6] [8]
Lutetium is a rare-earth element, with one naturally-occurring stable isotope 175 Lu and one naturally-occurring radioactive isotope 176 Lu. [3] When 176 Lu atoms are incorporated into earth materials, such as rocks and minerals, they began to be "trapped" while starting to decay. [4]
Euler's constant (sometimes called the Euler–Mascheroni constant) is a mathematical constant, usually denoted by the lowercase Greek letter gamma (γ), defined as the limiting difference between the harmonic series and the natural logarithm, denoted here by log:
The constants listed here are known values of physical constants expressed in SI units; that is, physical quantities that are generally believed to be universal in nature and thus are independent of the unit system in which they are measured.
