When creation scientists studied granite samples, they made interesting discoveries.a type of radiometer consisting of an evacuated glass bulb containing a set of lightweight vanes, each blackened on one side.Simulation of many identical atoms undergoing radioactive decay, starting with either 4 atoms per box (left) or 400 (right).The number at the top is how many half-lives have elapsed.
A process for determining the age of an object by measuring the amount of a given radioactive material it contains.
A 10 gram sample of U-238Now that has changed, and some important discoveries are being made.
When granite rock hardens, it freezes radioactive elements in place.
If one knows how much of this radioactive material was present initially in the object (by determining how much of the material has decayed), and one knows the half-life of the material, one can deduce the age of the object.
) is the time required for a quantity to reduce to half its initial value.
