What is the difference between radiation and radioactivity?

Answer 1

There is no difference in the meaning of the word. It is essentially the same thing. There are just two differenct forms of the word. You're still dealing with radium, Uranium, americium, and other radioactive elements either way.

Answer 2

Both are approaches for a nuclei to reach stability.

Radioactivity is the emission of radiation by the radioactive nuclei in its process to gain stability. This radiation could Alpha particles, beta particles (negative or positive), gamma electromagnetic radiation, neutrons, ect.

Fissionability is the splitting of a nuclide into two (rarely three) smaller nuclei plus other small particles as neutrons. This fission could be spontaneous fission or an induced fission (induced by e.g. neutron bombardment)

Answer 3

Radioactivity is the general property common to all radioactive materials. Radioactive is a qualifierused to identify materials having this general property.

Examples:

• The radioactivity of the sample was unusually high.
• Radioactive Carbon-14 levels in charcoal or bone can be used to determine age.

Answer 4

Ionization is the removal of electrons from extra nuclear part of the atom and is reversible process while Radioactivity is the disintegration of atomic nucleus and is irreversible process.

Answer 5

Radiation refers to the emission of energy in the form of waves or particles, while radioactivity is the property of certain elements to spontaneously emit radiation. Not all radiation is radioactive, but all radioactivity involves radiation.
