Radioactive Dating and the Use of Isotopes

Radiometric Dating and the Geological Time Scale: Contrary to creationist claims, it is possible to make that determination, as the following will explain:. Radioactive elements decay by half-lives. Also called radioactive dating. The temperature at which this happens is known as the closure temperature or blocking temperature and is specific to a particular material and isotopic system. Some nuclides are inherently unstable.

Note that it would be extremely unlikely for another dating method to agree on these bogus ages. Planetary Sciencespage After two half-lives one-fourth remains, after three half-lives, one-eighth, etc. The fact is that there are a number of Bible-believing Christians who are involved in radiometric dating, and who can see its validity firsthand.

It was first used inabout a century ago.

Radiometric dating techniques indicate that the Earth is thousands of times older than that--approximately four and a half billion years old. Creationists claim that argon escape renders age determinations invalid. By anyone's standards, 50 billion years is a long time. When the asteroids were formed in space, they cooled relatively quickly some of them may never have gotten very warmso all of their rocks were formed within a few million years.
