"The process of radiological dating has several intrensic flaws, the most glaring of which is that it assumes set levels of the isotopes measured between samples origionally. For example, in U238 dating, the U238 decays into lead. The only problem with dating samples based on the ratio of the two is that lead occurs natrually, and often in the company of uranium and other heavy metals. The ratio of natural lead to uranium is not constant ether, as lead can occur with little or no radiological involvement.
Basically, there is no way of predicting the actual decay time on the remaining U238, as extra natural lead is everywhere and probably with the uranium wherever it may manifest. This same inaccuracy is inherant in all other methods of radiological dating. Nothing says that the levels of carbon 14 are or were constant at any point in history, or that the levels of solar radiation that cause the isotope in the atmosphere were ever constant."
