Is radiometric dating reliable

other isotope pairs cover intermediate time periods between the spans for carbon 14 and uranium.

Some radiometric dating methods depend upon knowing the initial amount of the isotope subject to decay.

Together with stratigraphic principles, radiometric dating methods are used in geochronology to establish the geological time scale.

Evolutionists assume that the rate of cosmic bombardment of the atmosphere has always remained constant and that the rate of decay has remained constant.

Scientists place great faith in this dating method, and yet more than 50% of radiocarbon dates from geological and archaeological samples of northeastern North America have been deemed unacceptable after investigation.

Radiometric dating or radioactive dating is a technique used to date materials such as rocks or carbon, in which trace radioactive impurities were selectively incorporated when they were formed.

The method compares the abundance of a naturally occurring radioactive isotope within the material to the abundance of its decay products, which form at a known constant rate of decay.
