Does radiometric dating

In addition to the ages of Earth, Moon, and meteorites, radiometric dating has been used to determine ages of fossils, including early man, timing of glaciations, ages of mineral deposits, recurrence rates of earthquakes and volcanic eruptions, the history of reversals of Earth's magnetic field, and the age and duration of a wide variety of other geological events and processes.

There have been different methods of measuring carbon-14 since Willard Libby pioneered the radiocarbon dating technique in the 1940s – from the radiometric techniques of gas proportional counting and liquid scintillation counting to the more recent accelerator mass spectrometry (AMS).

When the weakly radioactive carbon-14 decays, it undergoes beta (β) decay producing nitrogen-14 and a beta particle.

Radiometric dating involves quantifying the amount of carbon-14 present by measuring the emitted beta particles from its radioactive decay.

Gas proportional counting involves converting samples to CO gas followed by detection and counting of the beta particles.

Radiometric dating works by determining the ratio of the number of isotopes of an element and the number of isotopes the element it turns into over time.

Since the rate at which certain elements decay and turn into different elements is understood, scientists are able to calculate the age of substances.

Liquid scintillation counting involves converting the sample into a carbon-rich liquid, which is then added to a scintillator.

When beta particles are emitted, the scintillator will emit a flash of light.

This is well-established for most isotopic systems.
