radioactive dating

noun

radioactive dating

A process for determining the age of an object by measuring the amount of a given radioactive material it contains. 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.

We date meteorites using the same tool of geology that we use to date Earthly rocks: radioactive dating.

The ages of the oldest known chemical elements are also approximately 15 billion years—a number that comes from radioactive dating techniques.

The Earth is generally assumed to be roughly 4.7 billion years old, utilizing radioactive dating that uses uranium decay, according to NASA.

The scientists were also surprised when they received results of the radioactive dating of 11 mounds.
