You need radioactivity, for many things such as x-rays.
Gamma radioactivity would be the most dangerous because, unlike alpha particles that can be blocked by paper or skin, and beta particles which can be shielded by foil, gamma radioactivity would need a lead shield. Plus gamma radioactivity effects organic material.
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.
Radioactivity has nothing to do with diffusion.
NO. Henri Becquerel was the discoverer of radioactivity.
