  schema:description "A radioactive metal, chemically almost identical to the widely-used lutetium-177, that gives off the same kind of medium-range particles plus a burst of extra very-short-range electrons. Those extra electrons may let it do more damage to a cancer cell than lutetium-177 while using the same delivery molecules."@en ;
