Half life and radiocarbon dating

Liquid scintillation counting is another radiocarbon dating technique that was popular in the 1960s.

In this method, the sample is in liquid form and a scintillator is added.

This scintillator produces a flash of light when it interacts with a beta particle.

A vial with a sample is passed between two photomultipliers, and only when both devices register the flash of light that a count is made.

Accelerator mass spectrometry (AMS) is a modern radiocarbon dating method that is considered to be the more efficient way to measure radiocarbon content of a sample.

In this method, the carbon 14 content is directly measured relative to the carbon 12 and carbon 13 present. Some inorganic matter, like a shell’s aragonite component, can also be dated as long as the mineral’s formation involved assimilation of carbon 14 in equilibrium with the atmosphere.

An age could be estimated by measuring the amount of carbon-14 present in the sample and comparing this against an internationally used reference standard.

Archaeology and other human sciences use radiocarbon dating to prove or disprove theories.Standard errors are also reported in a radiocarbon dating result, hence the “±” values.These values have been derived through statistical means.Radiocarbon Dating Groundwater The application of radiocarbon dating to groundwater analysis can offer a technique to predict the over-pumping of the aquifer before it becomes contaminated or overexploited.Tracer-Free AMS Dating Lab Beta Analytic does not accept pharmaceutical samples with "tracer Carbon-14" or any other material containing artificial Carbon-14 to eliminate the risk of cross-contamination.
