WebThe Uranium-238 Decay Series. Uranium-Thorium dating is based on the detection by mass spectrometry of both the parent ( 234 U) and daughter ( 230 Th) products of decay, through the emission of an alpha particle. The decay of Uranium 234 to Thorium 230 is part of the much longer decay series begining in 238 U and ending in 206 Pb.
