Yes. It is also fluorescent!
All uranium compounds are radioactive to some degree.
Zirconium does have radioactive isotopes, but the main ones used in industry are not radioactive.
Ordinary water is not radioactive, so it has no half-life.
All the isotopes of uranium are radioactive and unstable.
Yes. A radioactive atom is a radioactive atom. If that atom exists as a single atom and is uncombined and it is radioactive, it's radioactive. If that same atom is chemically combined with another or other atoms, it's still radioactive. It's just that simple.
Examples are: uraninite (pitchblende), carnotite, rutherfordite, coffinite, uranopilite, uranophane, autunite, torbernite, upalite, tyuyamunite, davidite.
Rocks are generally only dangerous if they fall on you, however, some rocks are poisonous. Asbestos, torbernite, and orpiment can all appear in rocks, making these rocks dangerous and potentially deadly.
"Radioactive."

Yes, it is possible for water to become radioactive if it comes into contact with radioactive materials or is contaminated by radioactive substances.
Zirconium does have radioactive isotopes, but the main ones used in industry are not radioactive.
