The aim of this web site is to explain radioactivity and its applications to the general public.

Beta (β) rays or beta electrons are electrons emitted spontaneously by some radioactive nuclei with an excess of neutrons : This is beta-minus (β-) radioactivity, the minus reminding that the electric charge of the electron is negative. Nuclei with an excess of protons emit anti-electrons or positrons beta positrons : This is the beta- plus radioactivity (β+) , a form of radioactivity rare in Nature.
