    Dating radioactive elements

    If you would like to set up information regarding a project in which radiocarbon dating illuminated or solved a problem or in which C14 played a central role, please contact [email protected] The Origins of Angkor Archaeological Project From the University of Otago (New Zealand) and the Fine Arts Department of Thailand, the project is concerned with investigating archaeology of pre-formative Angkorean society of South East Asia.Radiocarbon dating underpins the chronological aspects of the investigation.Learn about half-life and how it is used in different dating methods, such as uranium-lead dating and radiocarbon dating, in this video lesson. As we age, our hair turns gray, our skin wrinkles and our gait slows.However, rocks and other objects in nature do not give off such obvious clues about how long they have been around.Most systems promoted by Evolutionists involve radioactivity.Various radioactive elements are involved, including Carbon-14, Uranium-238, Thorium-232, and Potassium-40. The lowest age defended on a scientific basis is in the 6 to 10 thousand year range.

    The half-life of uranuim-238 is 4.5 billion years, since this object has gone through two half-lives it is 9 billion years old.

    It has been shown to reproduce accurate dates comparing to the known ages of antique artefacts, ancient ruins, etc.

    Look at the diagram below which represents the radioactive decay of uranium-238.

    And it does not work on rocks or thoroughly mineralized fossils; it is only useful for relatively well-preserved organic materials such as cloth, wood, and other non-fossilized materials.

    Other methods must be used to estimate the age of rocks and minerals.
