What is Radioactivity? – Definition and Types

What is Radioactivity? – Definition and Types The phenomenon of spontaneous emission of powerful radiation exhibited by heavy elements is called radioactivity. It is an irreversible self-disintegrating activity as the elements breaks itself up (fission reaction). The elements that exhibit this activity are called radioactive elements. Example of radioactive elements are uranium, radium, thorium, pulutonium, …
