175 Lu 174.940770 (3) 97.41 (2) oxide 98 - 99+

176 Lu 175.942679 (3) 2.59 (2) oxide 52 – 74+

Both Lutetium Isotopes are generally considered to be stable, although strictly speaking Lu-176 is not entirely stable with a half-life of 3.78 x 1010 years. Lu-175 can be used as a yield tracer in the ICP-MS based determination of Pu in urine. Lu-176 is used for the production of radioactive Lu-177 which is a very promising radio-immunotherapy isotope for the treatment of small, soft tumors.
