For example, for Carbon-14, it would take 5730 years for the 50% of the initial remaining to turn up to lose its capability in radioactive decay in order to have 50% of what has remained after the initial remaining to activate radioactive dating.

What if actual result of decay would not follow the sequence of 50% remaining rule in which it would take a shorter period to become inactive in decay instead of that 5730 years, using 5730 years as a base to presume that the decay would last in every half year would simply falsify the age that would be computed through radioactive dating method.

There are many different isotopes of carbon and one that we have probably heard of is in the form of carbon-14, known for radio-carbon dating, but where does this radioactive isotope come from?

Although there were no machines for detecting them systematically before 1935, cosmic rays have left their footprints in the geological record by creating radioactive elements such as the carbon-14 used in carbon-dating.

Using Argon-argon dating - a technique based on the decay ratio of radioactive potassium - researchers at the University of California Berkeley and the University of Glasgow have revised both the date of the dinosaur extinction 66 million years ago, and the timing of the Chicxulub asteroid impact that occurred at around the same time.

But dating things as old as this, which is done by studying the products of radioactive decay, is not a precise science.
