Customers from Germany and South Africa have ordered ytterbium-176. The isotope is used to manufacture lutetium-177 widely applied in medical diagnostics and therapy. “This time specification requirements for ytterbium-176 are much stricter. It should be at least 99.5% pure, with the content of certain elements being less than a ten thousandth of one percent, and we are preparing to meet them,” Alexander Shushkin, Head of Isotope Production, commented on the order.
