The three main assumptions that affect the results of radiometric dating are: 1) the rate of decay has always been constant, 2) there has been no contamination (no movement of elements into or out of the object over time), and 3) we can determine how much daughter element there was to begin with.[ii] There are many test results that make the reliability of these dating techniques very questionable.[iii] Naturalists try to explain these questionable results, but still can’t adequately explain them from their worldview.[iv] Evidence from “as far back as 1971” may show “that high pressure could increase decay rates very slightly for at least 14 isotopes.”[v] Naturalists even admit that radiocarbon dating does not work on living mussels because of the lack of new carbon in that environment.So what other situations and conditions create unreliable results that we must also throw out the dating because of?There are many assumptions that have to be made when using radiometric dating methods that might make these techniques unreliable.If any of these assumptions are wrong, then the reliability of the testing method can and should be put in question.
“The widespread emanation of C-free volcanogenic carbon dioxide after the Flood would have further inflated the carbon-14 dates of tree rings in a systematic manner in many parts of the world.”[vii] Naturalists have to assume whether wood remains were near volcanic vents or not.“For example, the radioactive decay of uranium in tiny crystals in a New Mexico granite yields a uranium-lead ‘age’ of 1.5 billion years.Yet the same uranium decay also produced abundant helium, but only 6,000 years worth of that helium was found to have leaked out of the tiny crystals.”[xix] Helium is created in radioactive decay reactions and should leak out of rocks rather quickly.He says this is an oversimplification and concludes that about 10 supernovae from over 6 billion years ago to about 200 million years ago contributed to the uranium stores on earth to produce the unique ratio of U-235/U-238.It seems it is impossible to ever know what were the initial amounts of U-238 and Pb-206.
