Radiometric dating research paper

Precision is enhanced if measurements are taken on multiple samples from different locations of the rock body.

By allowing the establishment of geological timescales, it provides a significant source of information about the ages of fossils and the deduced rates of evolutionary change.The procedures used to isolate and analyze the parent and daughter nuclides must be precise and accurate.This normally involves isotope-ratio mass spectrometry. The precision of a dating method depends in part on the half-life of the radioactive isotope involved.For most radioactive nuclides, the half-life depends solely on nuclear properties and is essentially a constant.It is not affected by external factors such as temperature, pressure, chemical environment, or presence of a magnetic or electric field.
