the isotope 14c is radioactive, and beta-decays with a half-life of 5,730 years. each radioactive isotope decays at its own fixed rate, which is expressed in terms of its half-life or, in other words, the time required for a quantity to fall to half of its starting value. this claim is true, the biblical account of a young earth (about 6,000 years) is. genesis 1 defines the days of creation to be literal days (a number with the word “day” always means a normal day in the old testament, and the phrase “evening and morning” further defines the days as literal days). note that, contrary to a popular misconception, carbon dating is not used to date rocks at millions of years old. that the earth experienced a global flood catastrophe which laid down. for example, with potassium-argon dating, we can tell the age of materials that contain potassium because we know that potassium-40 decays into argon-40 with a half-life of 1. carbon, uranium and potassium are just a few examples of elements used in radioactive dating. therefore, dating by this method is at best a hypothesis concerning the age of any rock suite or mineral; it is certainly not a scientific fact! with radiocarbon dating, we see that carbon-14 decays to nitrogen-14 and has a half-life of 5,730 years. two questions immediately arise: how do we know the age of the flux monitor, and how good is the assumption that 40k, 40ar, and 39ar are unaffected by the irradiation process? long does it take to get a phd in nursing? assumption 8 is strongly dependent on the methodology used and the personnel making the measurements. corrections for interfering isotopes in the 40ar/39ar dating method. other common isotopes used in radioactive dating are uranium, potassium and iodine.
