Thorium beta decay
WebOther articles where beta-minus decay is discussed: radioactivity: Beta-minus decay: In beta-minus decay, an energetic negative electron is emitted, producing a daughter nucleus of one higher atomic number and the same mass number. An example is the decay of the uranium daughter product thorium-234 into protactinium-234: WebThorium metal is the preferred chemical form for post-irradiation processing of the target, ... 3.6 d, and 11.4 d, respectively). Of these, 228 Ra and 225 Ra beta-decay to actinium isotopes, while the others alpha-decay to radon isotopes. Use of this mixture as a radium-actinium generator will produce 225 Ac free of 227 Ac. While 228 Ac ...
