Radioactive dating facts

By knowing how much carbon 14 is left in a sample, the age of the organism when it died can be known.It must be noted though that radiocarbon dating results indicate when the organism was alive but not when a material from that organism was used.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.It is rapidly oxidized in air to form carbon dioxide and enters the global carbon cycle.Plants and animals assimilate carbon 14 from carbon dioxide throughout their lifetimes.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 sample is in liquid form and a scintillator is added.

Background radiocarbon activity is measured, and the values obtained are deducted from the sample’s radiocarbon dating results.

Background samples analyzed are usually geological in origin of infinite age such as coal, lignite, and limestone.

Standard errors are also reported in a radiocarbon dating result, hence the “±” values.

These values have been derived through statistical means.

Over the years, carbon 14 dating has also found applications in geology, hydrology, geophysics, atmospheric science, oceanography, paleoclimatology and even biomedicine.
