Kegunaan isotop molibdenum
- 95Mo is used to produce medical radioisotope 97Ru via the 95Mo (4He, 2n) 97Ru reaction. The isotope 99Mo is commercially produced by the fission of 235U and is the parent radionuclide of 99mTc, which is the most widely used radiopharmaceutical in the world. The much longer half-life of 99Mo (about 66 h) enables the radionuclide to be transported more easily than the short-lived (6 h half-life) 99mTc. The n(99Mo)/n(99mTc) amount-ratio generator was originally developed at Brookhaven National Laboratory (Fig. IUPAC.42.2) in the early 1960s and is now a patented system.
