RADIOACTIVE WASTE

A general public knowledge base dedicated to radioactivity created and maintained by the french physics community

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.
