Isotope dating wiki

The rate at which radioactive elements decay is governed by the exponential decay constant.The amount of time required for half of a given quantity of a parent radioactive element to decay into the daughter product is referred to as the half-life.With our focus on one particular form of radiometric dating—carbon dating—we will see that carbon dating strongly supports a young earth.

Calibration Software Probability Density Function Tree rings and other calibration records Wiggle-Matching: Using fluctuations in calibration curve to obtain precise ages relatively-dated series.Thermochronometry involves comparing the radiometric dates of two or more minerals with different closure temperatures.Before we get into the details of how radiometric dating methods are used, we need to review some preliminary concepts from chemistry.Recall that atoms are the basic building blocks of matter.Many people have been led to believe that radiometric dating methods have proved the earth to be billions of years old.

This has caused many in the church to reevaluate the biblical creation account, specifically the meaning of the word “day” in Genesis 1.

The different methods of radiometric dating are accurate over different timescales, and they are useful for different materials.

After one half-life has elapsed, one half of the atoms of the nuclide in question will have decayed into a "daughter" nuclide, or decay product.

In many cases, the daughter nuclide is radioactive, resulting in a decay chain.

This chain eventually ends with the formation of a stable, nonradioactive daughter nuclide.

It is based on a comparison between the observed abundance of a naturally occurring radioactive isotope and its decay products, using known decay rates.
