spontaneous disintegration of atomic nuclei
Yes.
spontaneous decay of unstable atomic nuclei.
It is a man-made element and, due to its high radioactivity does not exist in nature.

The primal heat from the deep interior of the Earth is mainly due to radioactive decay, with a small contribution due to gravity compression.
Radioactivity affect the water molecules. Radioactivity makes it harmful
the tilt of the earth on 23.5 degrees and it rotating the sun
What other sort of radioactivity is there?
It occurs due to the instability of the element. It is a spontaneous process. Radioactive atoms are known as isotopes.
Radioactivity can be induced in ordinary matter by artificial transmutation.
no but she built the knowleage of radioactivity.
You cannot measure radioactivity in litres
