The object's approximate age can then be figured out using the known rate of decay of the isotope.
Radiocarbon dating is one kind of radiometric dating, used for determining the age of organic remains that are less than 50,000 years old.
A method for determining the age of an object based on the concentration of a particular radioactive isotope contained within it.
The amount of the isotope in the object is compared to the amount of the isotope's decay products.
The Committee first met in December 1923 and then began publishing in "Annual Reports," reviewing and discussing all the papers on radiometric dating during each successive year, continuing until 1955 or so.
The development of radiometric dating during the early decades of the 20th century, however, soon displaced all these arguments, since the latter method seemed to allow much more time for evolution.
As this dating method began to be developed, a Committee on the Measurement of Geologic Time was formed by the National Research Council with Professor Alfred C.
For those Christians who believe that Genesis (like the other historical books of the Bible) should be understood as literal history, it has therefore been necessary to show the fallacies in the so-called "scientific proofs" of an old earth.
Before the discovery of radioactivity, this usually meant arguing against the evidences from crustal cooling, sedimentation rates, or salt influx in the oceans.
