Minerals that glow in the dark may or may not be radioactive. There are some other reasons that a mineral could glow in the dark without it being radioactive. Certainly if a material is radioactive enough it will glow in the dark. But note that some radioactive materials are only weakly radioactive, and an observer will not be able to see them glow in the dark.

The kind that need to be "charged up" by exposure to light and go dark after a few minutes to an hour or so are not radioactive.
