Yes, water can be radioactive. In fact, on Earth, just about any water you normally find has at least traces of radioactive tritium in it. But it can also have radioactive oxygen, and any of a large number of other radioactive things in it. This is natural, and not necessarily the result of any human activity.
There is a link below to an article on background radiation, which is normal radiation normally found in nature.
i think being radio active(not being exposed to radiation, but actuly being radioactive) would kill you. i think this would affect your ability to float. i forget if dead people float or sink, but living people can affect their boencey, so yes it would, as dead people cannot affect their bouencey.
It can be. Rain contains small amounts of dust from the atmosphere. If there is radioactive dust in the air, perhaps following a nuclear explosion, then it may be carried down in the rain.
If its boyant or not.
the ability to float with density is almost impossible
Salt water has salt (!) in it, ego it is denser and takes more weight to displace it; the reason things float in whatever. The denser the liquid, the higher things float

density. A less dense object will float on a more dense liquid.

yes
Yes, water density will affect an object's ability to float.
