You know what a radioactive isotope is?

There was a flurry of research and development of new radionuclides and radiopharmaceuticals for use with the imaging devices and for in vitro studies5.

These spaces are now known, respectively, to be the places of the radioactive synthetic elements technetium and promethium, and also the last two quite rare naturally occurring stable elements hafnium (discovered 1923) and rhenium (discovered 1925).
