The age of a sample is given by the age equation: where λ is the radioactive decay constant of K (approximately 5.5 x 10 year , corresponding to a half-life of approximately 1.25 billion years), J is the J-factor (parameter associated with the irradiation process), and R is the Ar*/ Ar ratio. The J factor relates to the fluence of the neutron bombardment during the irradiation process; a denser flow of neutron particles will convert mor… WebWe can use a formula for carbon 14 dating to find the answer. Where t 1/2 is the half-life of the isotope carbon 14, t is the age of the fossil (or the date of death) and ln () is the natural logarithm function. If the fossil has 35% of its carbon 14 still, then we can substitute values into our equation. So, the fossil is 8,680 years old ...
