Autunite is a mineral containing Uranium and is therefore radioactive.
Autunite is not magnetic. It is a hydrated calcium uranyl phosphate mineral that does not exhibit magnetic properties.
Uranium minerals as pitchblende, uraninite, carnotite, autunite, davidite, etc. or as a secondary product from the mining of gold, vanadium, phosphates.
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.
Autunite is not magnetic. It is a hydrated calcium uranyl phosphate mineral that does not exhibit magnetic properties.
