The simplicity of this equation combined with the fact that it works with many different dating methods produces great confidence in its reliability.
This produces an exponentially decreasing curve as described by the equation and displayed as the decreasing curved line in figure 2.A calendar can't measure time in the one-hundred-meter race, and a stopwatch can't measure the days before Christmas.As with other timepieces, radiometric-dating methods must be appropriate to the sample being dated.Though most atoms contain stable nuclei and do not decay, some types do.When radioactive decay occurs, no one can predict which individual atoms will decay when.All radiometric dating is based on this very simple equation and the exponentially decreasing curve.
In other words, N is the present abundance of parent atoms, the original abundance of parent atoms equals N, t is time, and k is a constant related to the half-life (the time it takes for half of the parent atoms of a radioactive isotope to decay). A sign tells her that the Tyrannosaurus Rex is millions of years old. Debunking mysterious and complicated explanations of radiometric dating can be accomplished with a simple understanding of its general principles. Wiens Bewildered, Janet watches her son gaze in awe at the dinosaur exhibit. Yet, many people challenge the accuracy of radiometric dating, and misinformation describing the various radiometric techniques abounds.The uncertainty levels of these half-lives are very small—only about plus or minus 2 percent for all except for rhenium (5%), lutetium (3%), and beryllium (3%).At this level of certainty, though an age may vary by a small percentage, no question remains as to whether Earth was created recently, or a long time ago.However, one significant difference exists between radiometric dating and the hourglass design.
