Artificial Radioactivity

During the artificial transmutation of elements, it is observed that quite often the product obtained is also radioactive, though its half-life period is usually very small. This phenomenon in which the artificial disintegration of a stable nucleus leads to the formation of a radioactive isotope is called artificial radioactivity.

It may be mentioned that as the radioactive isotopes formed by the artificial transmutation have usually very short half-life periods, they are very rare in nature. This is because as soon as they are formed, they decay. In some cases, instead of positrons, electrons (P particle) are emitted by the artificial radioactive isotopes produced.

Natural Radioactivity

Artificial Radioactivity

It involves spontaneous disintegration of unstable nuclei with emission of a or a p particles or у radiations giving rise to new nucleus.

It cannot be controlled.

It is shown by the elements with high atomic number and mass number.

Here, stable nuclei are bombarded with high-energy particles to produce radioactive elements.

It can be controlled by controlling the speed of the bombarding particles.

It can be induced even in the lighter elements.
