Radiocarbon Dating and the Bible Is carbon dating or radiocarbon dating always reliable and beyond question? Are all radioactive dating methods unreliable? Have carbon C 14 dates millions of years old been proven wrong? Is carbon dating useless before 2, B.
Since , scientists have reckoned the ages of many old objects by measuring the amounts of radioactive carbon they contain. New research shows, however, that some estimates based on carbon may have erred by thousands of years. It is too soon to know whether the discovery will seriously upset the estimated dates of events like the arrival of human beings in the Western Hemisphere, scientists said. But it is already clear that the carbon method of dating will have to be recalibrated and corrected in some cases. They arrived at this conclusion by comparing age estimates obtained using two different methods - analysis of radioactive carbon in a sample and determination of the ratio of uranium to thorium in the sample.
Whenever the worldview of evolution is questioned, the topic of carbon dating always comes up. Here is how carbon dating works and the assumptions it is based upon. Radiation from the sun strikes the atmosphere of the earth all day long. This energy converts about 21 pounds of nitrogen into radioactive carbon This radioactive carbon 14 slowly decays back into normal, stable nitrogen.
Radioactive, decay constants dating be determined by comparing isotope data for dating of known age. This method requires at least one of the isotope systems to be very dating calibrated, such as the Pb-Pb system. The basic equation radioactive radiometric dating requires that neither the parent nuclide nor the daughter product can enter dating leave the radioactive after its formation. The possible confounding effects of contamination of parent and daughter isotopes have to be considered, as do the effects of any loss or gain of such isotopes since the sample was created.
