IR-U Uranisotoper (U-234, U-235, U-238) i vatten. Provtyp: Vatten. Analystyp: Isotoper
Uranium-238, uranium-235, and thorium-232 have long half-life (238 U: 4.5×10 9 years, 235 U: 7.04×10 8 years, 232 Th: 1.4×10 10 years). Otherwise, they would not exist in nature today because some 10 9 years have already passed since the origin of the elements.

Since too few neutrons are born from fission at the energy required to fission U-238 (and other non-fissile isotopes), a reaction with only U-238 is not sustainable. All neutrons can cause fission in U-235, so its reaction is sustainable.

Carbon 14 and Uranium 238 are not used together to determine fossil ages. Carbon 14 with a half life of 5,700 years can only be used to date fossils of approximately 50,000 years. Most fossils are thought to be much older than 50,000 years. Also most fossils no longer contain any Carbon. The fossilized remains have been mineralized where the original organic material has been replaced and
