The amount of K − 40 present for the given rock sample is to be determined. Concept Introduction: For calculating the age of a rock sample, radiological dating is taken into consideration, which is based on the half-lives of radio nuclides. It uses radiological dating pair of isotopes that undergo ‘parent’ to ‘daughter’ radioactive disintegrations. The most commonly used isotopes for such purposes are K − 40 and Ar − 40 . K − 40 is a naturally occurring radionuclide while Ar − 40 is one of the daughter disintegrations of K − 40 .
