226Ra\\\/230Th method is used to date continental Naturally occurring uranium metal has 3 major isotopes, 235U (0.71 percent), 238U (99.28 percent abundance), and 234U (0.0054 percent). The isotopes of uranium are radioactive. 235U is the only naturally occurring fissile isotope while 238U is the most stable isotope of uranium metal which makes up to 99% of the naturally occurring uranium. 233U is another fissile isotope that can be produced However, the gas diffusion or gas centrifuge processes for $\ce{^235U}$ enrichment do not only lead to an increase in the $\ce{^235U}$ concentration in the fuel, but also to a more than proportional increase in the $\ce{^234U}$ concentration.
