3-6: Uranium Thorium dating While radiocarbon dating is limited to about <50 000 y and the 40K- Ar dating method is limited to volcanic material and also used to be limited to samples of more than 100 000 y of age, the Uranium Thorium method is an alternative approach to extend the radiocarbon dating range to 1 000 000 y in time. uranium thorium
Get Price[...]Uranium–thorium dating, also called thorium-230 dating, uranium-series disequilibrium dating or uranium-series dating, is a radiometric dating technique established in the 1960s which has been used since the 1970s to determine the age of calcium carbonate materials such as speleothem or coral.
Get Price[...]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.

Get Price[...]The thorium fuel cycle is a nuclear fuel cycle that uses an isotope of thorium, 232 Th, as the fertile material.In the reactor, 232 Th is transmuted into the fissile artificial uranium isotope 233 U which is the nuclear fuel.Unlike natural uranium, natural thorium contains only trace amounts of fissile material (such as 231 Th), which are insufficient to initiate a nuclear chain reaction.
