Transformation of Elements
There are two types of radioactivity – natural and artificial radioactivity.
The phenomenon of radioactivity was first discovered by Henri Becquerel
Natural radioactivity is the spontaneous disintegration of the nucleus of an atom during which α-particle or β-particle, or gamma rays or a combination of any or all the three and heat (or energy) are released.
