Reliability of radiometric dating
It is a reliable and accurate way to determine the ages of rocks.
These and numerous other claimed anomalies in radiocarbon dating are explained in detail in Mark Isaak's book [Isaak2007, pg. In short, while like any other method of scientific investigation, radiocarbon dating is subject to anomalies and misuse, when used correctly in accordance with well-established procedures and calibration schemes, the method is a very reliable means of dating relatively "recent" artifacts.I have read several blog sites in which there is discussion on the age of the earth and inevitably the topic of the dating of rocks and the reliability of this method and it's data is questioned.Radiometric dating relies on the natural decay of radioactive isotopes.In 2009, several leading researchers in the field established a detailed calibration of radiocarbon dating, based on a careful analysis of pristine corals, ranging back to approximately 50,000 years before the present epoch [Reimer2009].Here is a graph showing radiocarbon dates on the vertical axis and the calibrated age on the horizontal axis (shown here with permission from Johannes van der Plicht, one of the authors of the 2009 study).
It results in a decrease over time of the original amount of the radioactive material.
