Chernobyl is well-known for it's dangerously high radioactivity levels.
Henri Becquerel first discovered radioactivity (by mistake).
Examples of mineral characteristics: - density - hardness - refractive index - chemical composition - magnetic properties - cleavage - crystal system - radioactivity

radioactivity start from the nucleus of an atom which becomes unstable n emit radiation
color, hardness, chemical composition, system of crystallization, refractive index, luster, magnetic properties, radioactivity, fracture characteristics, etc.
Examples of the characteristics of matter: state of matter, density, radioactivity, thermal properties, electrical properties, optical properties, chemical composition, etc.
There are actually quite a few properties to classify rocks and minerals. Some of these are chemical composition, radioactivity, phosphorescence, grain size, hardness, color, streak and fluorescence.
William Horace Ross has written: 'On the relation between the radioactivity and the composition of thorium and uranium minerals ..' -- subject(s): Radioactive substances
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
