WebApr 11, 2024 · We can define radioactivity as the spontaneous disintegration of unstable atomic nuclei with the emission of alpha (α), beta (β), or gamma (γ) radiations and the release of energy. Additionally, we can say that radioactivity is a natural process that occurs in certain elements, such as uranium and thorium, and their unstable nuclei.

In 1815, the Swedish chemist Jöns Jacob Berzelius analysed an unusual sample of gadolinite from a copper mine in Falun, central Sweden. He noted impregnated traces of a white mineral, which he cautiously assumed to be an earth (oxide in modern chemical nomenclature) of an unknown element.
