Essay on radiometric dating

Player
Short video description
Recent puzzling observations of tiny variations in nuclear decay rates have led some to question the science of using decay rates to determine the relative ages of rocks and organic materials. Scientists from the National Institute of Standards and Technology NIST , working with researchers from Purdue University, the University of Tennessee, Oak Ridge National Laboratory and Wabash College, tested the hypothesis that solar radiation might affect the rate at which radioactive elements decay and found no detectable effect. Atoms of radioactive isotopes are unstable and decay over time by shooting off particles at a fixed rate, transmuting the material into a more stable substance. For instance, half the mass of carbon, an unstable isotope of carbon, will decay into nitrogen over a period of 5, years. The unswerving regularity of this decay allows scientists to determine the age of extremely old organic materials -- such as remains of Paleolithic campfires -- with a fair degree of precision.

Contrast relative dating and radiometric dating -

The topic of radiometric dating and other dating methods has received some of the most vicious attacks by young earth creation science theorists. However, none of the criticisms of young earth creationists have any scientific merit. Radiometric dating remains a reliable scientific method. To broaden your learning experience, we provide links to resources on other old earth websites, noted below by this graphic - Article Submission Policy. Roger Wiens.

Carbon dating is radiometric dating, using the carbon 14 isotope. Carbon 14 is used for fossils of fairly recent origin, as it becomes less and less accurate beyond 10 half lives about 50 thousand years. One half-life of carbon 14 is about years.
