Nuclear Radiation

Discovery:

Henry Becquerel discovered radioactivity accidentally in 1896.

 

Nuclear radiation:

Some elements contain atoms with unstable nuclei. With time, the unstable nucleus disintegrates. While doing so, it shoots out a tiny particle and sometimes wave energy as well. Since the particles and the waves radiate from the nucleus, it is called nuclear radiation.

 

Radioactive isotopes:

These are particular isotopes of an element whose atoms have different number of neutrons in the nucleus.

 

List of radioactive isotopes:

Three main types of nuclear radiation:

Alpha particles (α) , Beta particles (β) and Gamma rays (γ)
