Ytterbium (Yb-176)
Ytterbium-176 (Yb-176) is a stable, non-radioactive isotope of ytterbium, with a mass number of 176. It’s a naturally occurring isotope and is also produced by fission. Ytterbium-176 is a crucial precursor for the production of Lutetium-177 (Lu-177), a beta-emitting radiopharmaceutical used in targeted radiotherapy, particularly for prostate and other cancers.
