Professor Radium was a Batman villain who later joined the Nuclear Legion.

Professor Henry Ross was a scientist who was accidentally transformed into "a human radium ray". In need of an expensive antidote, Ross used his newfound powers to commit crimes in Gotham City, anxious not to hurt anyone, but accidentally killing various people in the process. Going insane, Professor Radium found himself battling Batman and Robin. After a long chase and struggle, he is apparently killed.[1]

Ross returned some time later and he joined a subgroup of the villainous Society known as the Nuclear Legion.
