Correlating radioisotope dating methods

Rated 4.7/5 based on 677 customer reviews

A research consortium has recently convened at ICR to go further and develop a workable understanding of the radioisotope decay data from a young-earth perspective.

The old-earth model doesn't work, and a better model must replace it.

Its results have been shown to be inconsistent, discordant, unreliable, and frequently bizarre in any model.

Creationists have, in particular, pointed out the weak assumptions on which the method is based, and the contradictory nature of its results.

Many are also unaware that Bible-believing Christians are among those actively involved in radiometric dating.

magazine has been continuously published since 1978, we are publishing some of the articles from the archives for historical interest, such as this.

The basic theory of radiometric dating is briefly reviewed.

Since 1955 the estimate for the age of the Earth has been based on the assumption that certain meteorite lead isotope ratios are equivalent to the primordial lead isotope ratios on Earth.

Many Christians have been led to distrust radiometric dating and are completely unaware of the great number of laboratory measurements that have shown these methods to be consistent.Many atoms (or elements) exist as numerous varieties called isotopes, some of which are radioactive, meaning they decay over time by losing particles.Radiometric dating is based on the decay rate of these isotopes into stable nonradioactive isotopes.For teaching and sharing purposes, readers are advised to supplement these historic articles with more up-to-date ones suggested in the Related Articles and Further Reading below.Before 1955, ages for the Earth based on uranium/thorium/lead ratios were generally about a billion years younger than the currently popular 4.5 billion years. old Earth is reviewed and deficiencies of the uranium/lead method are discussed.
