Radioactivity
Radioactivity is the phenomenon in which some unstable nuclei transform into others with the emission of particles. Radioactivity is as old as the Universe and is present everywhere: in the stars, in the Earth and in our own bodies. In fact, man has been exposed to radiation since when he appeared on Earth. Radioactivity was discovered at the end of the 19th Century thanks to the work of Henry Becquerel and Pierre and Marie Curie who in 1903 received the Nobel Prize in Physics for their important contribution to scientific knowledge. They discovered that certain minerals possessed the property of spontaneously emitting radiation: these minerals, such as uranium, radium and polonium, for example, were called “active” and the phenomenon regarding the emission of radiation was called “radioactivity”.
