Radiation vs Radioactivity

Hi guys, today I would like to share with you all about the difference between radiation and radioactivity. Some of us still cannot differentiate between radiation and radioactivity.

Radioactive man !!!!

First of all, we look the definition Radiation and radioactivity.

Radiation :

Particles emitted in atomic or nuclear processes (neutrons, gammas–photons of nucleus origin, x-rays–photons of atomic origin, b-particles–electrons or positrons , a-particles–helium nuclei, heavy charged particles–e.g. FP)

Radioactivity:

A specific type of nuclear processes in which a nucleus spontaneously decay, emitting radiation in the process.

The radiation and radioactivity are related to each others. The ability to generate radiation is called radioactivity, while substances that possess this radioactivity are called radioactive substances.

For more clear, we take a look one example:

We taking the electric bulb as familiar example, where the light bulb would be the radioactive substances, the light rays emitting from the light bulb are the radiation, and the ability to generate the light is radioactivity.

Radiation can include alpha rays, beta rays, and gamma rays. The figures show the ability of the alpha rays, beta rays, and gamma rays.

 

The nucleus of a radioactive substance decays whenever it emits radiation, mutating successively into other substances until it reaches one that is not radioactive. 

The method used to for measuring the life of radioactive substance is called half life. Half life is the time required for the original radioactive level to weaken by one-half.

Figure show the unit of the radiation.
