Rhenium has one stable isotope, rhenium-185, which nevertheless occurs in minority abundance, a situation found only in two other elements (indium and tellurium). Naturally occurring rhenium is only 37.4% 185 Re, and 62.6% 187 Re, which is unstable but has a very long half-life (~10 10 years).
They also found rhenium in gadolinite and molybdenite. [5] In 1928 they were able to extract 1 gram of the element by processing 660 kg of molybdenite. In 2020 a memorial medal of the discovery was issued by ISTR (art-designer: Igor Petrov).
Rhenium (186Re) Obisbemeda is a Rhenium-186 radiolabeled therapeutic targeting recurrent glioblastoma, leptomeningeal metastases, and pediatric brain cancers. Their BMEDA loading technology coupled with Rhenium-186 allows for the entrapment the radiation particle within a nanoliposome carrier, facilitating accumulation and retention in the ...

Rheniite is one of the first minerals of the element rhenium to be found. The other known approved rhenium mineral is the sulfide mineral tarkianite. Almost all commercially mined rhenium is retrieved as a by-product of molybdenum mining as rhenium occurs in amounts up to 0.2% in the mineral molybdenite. A discredited rhenium sulfide known as ...
Naturally occurring rhenium (75 Re) is 37.4% 185 Re, which is stable (although it is predicted to decay), and 62.6% 187 Re, which is unstable but has a very long half-life (4.12×10 10 years). [4] Among elements with a known stable isotope, only indium and tellurium similarly occur with a stable isotope in lower abundance than the long-lived ...
