Ordinary phosphorus found in nature is not radioactive. Like all other elements, radioactive synthetic isotopes of phosphorus have been made.
Yes, phosphates ores contain radium - as a progeny of uranium in the deacy chain.
Phosphorescence occurs in places all over the world and it happens when small micro organisms " glow" in the water. These plankton like creatures come from the bottom of the ocean where it's dark so they only come out at night. I have seen phosphorescence in the puget sound before and it occurs around the middle of august in the summer but in the sound it only happens in summer. Most of the times I have noticed it's a clear night with no rain.
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.
All uranium compounds are radioactive to some degree.
Zirconium does have radioactive isotopes, but the main ones used in industry are not radioactive.
As radium is radioactive, radium chloride would also be radioactive. Any compounds make with any radioactive material are radioactive, and they cannot be "not" radioactive. Radioactive material doesn't really care if it is "alone" or in compound; it will be radioactive in any case.

Phosphorescence is a process in which the energy absorbed by a substance is released slowly in the form of light - a process used, for example, by glow-in-the-dark materials.
