Here is the quote from the AIG text. Will you accept this or do I have to quote the whole chapter so you can't claim I took it out of context?
"After a mineral containing uranium atoms is formed, the products of uranium decay begin to collect in the mineral. The age of the mineral is found by determining the ratio of the parent material (238U) to the end product (206Pb). Special equipment must be used for determining uranium-to-lead ratios. In using this method, it is assumed that none of the lead escapes from the mineral, that no outside lead is added, and that no lead from a non-radioactive source was present to begin with. If any of these conditions have affected the sample being tested, the results will not be accurate."
