Scientists must use several assumptions to arrive at a date: At the time of origin, there was only Uranium, and no daughter elements.
The sample was always in a closed environment, so that all the measured daughter elements arose from the uranium decaying in the sample. Lack of Agreement Between Dating Methods Similar assumptions apply to all the various radiometric dating techniques. The uranium actually creates two products in the decay process—lead and helium.
Carbon 14 and carbon 12 (the stable form) are present in the atmosphere and are metabolized into the bodies of all living things in the same ratio as in the atmosphere.
Scientists date rocks by measuring the uranium and its decay products.
Carbon Dating Summary Radiocarbon dating is not an accurate method.
Radiocarbon is one of many cosmogenic isotopes that are used for dating. These are: Helium Beryllium Neon Aluminum Chlorine Calcium Iodine There are additional problems with radioactive isotope dating which I will investigate in the next few slides.
Fission track dating is somewhat of an anomaly in the field of radiometric dating.
Within their research, the ICR research team makes many claims that geological evidence, including their findings dealing with dating rocks using the fission track dating method, provides substantial evidence for a young earth.
