Investing in Dubnium

Dubnium is a synthetic element that is highly radioactive. The most stable isotope is dubnium-268, which has a half-life of 32 hours. It was first produced in Dubna, Russia by bombarding americium-243 with neon-22. In 1970, Americans at UC Berkeley synthesized dubnium by bombarding californium-249 with an 84 MeV beam of nitrogen nuclei.
