For example natural and artificial radioactivity.
No, radioactivity cannot be canceled. Radioactivity is a natural process where unstable atomic nuclei release energy in the form of radiation. While the rate of radioactivity can decrease over time as the unstable nuclei decay, the process itself cannot be canceled.
A scientist who studies radioactivity is called a nuclear physicist or a radiologist.
Henri Becquerel was a French scientist who was credited for the discovery of radioactivity. He was credited in 1896.
Marie Curie is famous for discovering radioactivity in 1898. She was a pioneering physicist and chemist who conducted groundbreaking research on radioactivity, earning her two Nobel Prizes in Physics and Chemistry.
The physicist who invented the Geiger counter, the instrument that detects radioactivity, was Hans Geiger.
Uranium is not artificial radioactivity so it is not clear what the question is about.

The bombardment of U-235 isotope with a nucleus, releasing tremendous amount of energy.
Several examples are uranium, thorium, radon, actinium, protactinium, plutonium, americium, etc.
Radioactivity affect the water molecules. Radioactivity makes it harmful
What other sort of radioactivity is there?
Radioactivity can be induced in ordinary matter by artificial transmutation.
no but she built the knowleage of radioactivity.
You cannot measure radioactivity in litres
Radioactivity in Japan is about 15,000 terabecquerels.
