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: WebDefinition and Formula.

WebJan 1, 2014 · The two uranium isotopes, 238 U and 235 U, decay into lead, 206 Pb and 207 Pb, with a half-life of 4.5 and 0.71 billion years, respectively. Characteristic lines for the γ-spectrum of the 238 U decay series, for example, are produced by the daughter element bismuth, 214 Bi, at 609 keV, 1 120 keV, and 1 764 keV.
