5.6.1. Radioactive Pollution


Radioactivity is a phenomenon of spontaneous emission of proton (a-particles), electrons (E-particles) and gamma rays (short wave electromagnetic waves) due to disintegration of atomic nuclei of some elements. These cause radioactive pollution.

Radioactivity:


Radioactivity is a property of certain elements (radium, thorium, uranium etc.) to spontaneously emit protons (alpha particles) electrons (beta particles) and gamma rays (short-wave electromagnetic wave) by disintegration of their atomic nuclei (nuclides).
