Carbon dating fossil Meetroom chatroulette
At high geomagnetic latitudes, the carbon-14 spreads evenly throughout the atmosphere and reacts with oxygen to form carbon dioxide.Carbon dioxide also permeates the oceans, dissolving in the water.Half the original quantity of carbon-14 will decay back to the stable element nitrogen-14 after only 5,730 years.(This 5,730-year period is called the half-life of radiocarbon, Figure 1).1 2 At this decay rate, hardly any carbon-14 atoms will remain after only 57,300 years (or ten half-lives). One of the most frequent uses of radiocarbon dating is to estimate the age of organic remains from archaeological sites. Carbon dating, also known as radiocarbon dating, is a method of estimating the age of carbon-bearing materials up to 60,000 years old.Most laboratories measure radiocarbon with a very sophisticated instrument called an accelerator mass spectrometer, or AMS.It is literally able to count carbon-14 atoms one at a time.3 This machine can theoretically detect one radioactive carbon-14 atom in 100 quadrillion regular carbon-12 atoms! AMS instruments need to be checked occasionally, to make sure they aren’t also “reading” any laboratory contamination, called background.
It’s a dilemma for evolutionists, who believe the rocks are millions of years old. Radiocarbon (carbon-14) is a very unstable element that quickly changes into nitrogen.
So rock samples that should read zero are occasionally placed into the instruments to test their accuracy.
