Compare and contrast relative and radioactive dating having problem updating t mobile
But YE scientists point out some anomalies in relation to C-14 and a very old earth.For instance, measurable amounts of C-14 have been found in fossil material, such as coal (traditionally Carboniferous period c300 mya).Radioactive parent (P) atoms decay to stable daughter (D) atoms e.g.the carbon isotope C-14 decays to nitrogen-14 and the uranium isotope U-235 decays to the lead isotope Pb-207.Mathematically, P = Po exp(-lambda T), where lambda = the decay constant and T = the period of decay. a zero initial number of D atoms, where P(or D) = the current number of P(or D) atoms, it follows that the age of a rock or mineral is computed as T=(1/lambda)ln(1 D/P).
The implication is that this organic material was either contaminated by new C-14, or it was buried much more recently and OE dating methods are suspect.This implies the earth is at least 20 million years old.Astronomical cycles can also be used to measure relative age.This challenge is mainly headed by Creationism which teaches a young-earth (YE) theory.A young earth is considered to be typically just 6,000 years old since this fits the creation account and some dating deductions from Genesis.
In other words, half of the radioactive isotope in a sample would have decayed to Nitrogen-14 (N-14) in just 5,730 years.
