Radioactivity is important for a number of reasons. It is the basis of both nuclear power and nuclear weapons. It allows for such things as medical X-ray examinations. Radioactive decay in the interior of the planet Earth is the source of the heat which causes the mantle to be liquid, and thereby causes continental drift, and earthquakes and volcanoes. None of those would exist without radioactivity. The study of radioactivity has provided scientists with many vital clues about the structure of atoms, and the behavior of subatomic particles.

Radioactivity affect the water molecules. Radioactivity makes it harmful
What other sort of radioactivity is there?
For example natural and artificial radioactivity.
Radioactivity can be induced in ordinary matter by artificial transmutation.
You cannot measure radioactivity in litres
Radioactivity in Japan is about 15,000 terabecquerels.
Human + A lot of radioactivity = Dead
Artifical radioactivity
no but she built the knowleage of radioactivity.
You need radioactivity, for many things such as x-rays.
