Summary Introduction

**To explain:** During a radiometric dating of a rock, if nine consistent results invalidate one inconsistent result or the inconsistent result invalidates the other nine consistent ones.

**Concept introduction:** Half-life is the time taken for one-half of atoms of radioactive isotope to decay, which is a characteristic of a radioisotope. The radiometric dating is a technique by which the fossils or age of a rock can be determined using the half-life calculations.
