Most radiocarbon dating labs have liquid scintillation counters for radiometric…The history of radiocarbon dating goes back to 1949, where it was introduced to the world by Willard Libby.Once the radiocarbon atom is produced, it rapidly combines with oxygen (OC (7 neutrons) atoms. Carbon atoms are incorporated into plant tissue (by photosynthesis) then into animal tissue (by ingestion) in nearly the same ratio as in the atmosphere. The Earth's magnetic field, its history, origin and planetary perspective. Nitrogen atoms high in the atmosphere can be converted to radiocarbon if they are struck by neutrons produced by cosmic ray bombardment.

Thus the additional dating of the paint reveals the forger’s scheme where the repainting of an appropriately aged canvas was used to convey the illusion of authenticity.Since the carbon in these fuels was ancient, it contained no radiocarbon. Therefore, prior to atmospheric bomb testing, the proportion of radiocarbon to C was relatively low, giving relatively old ages. Ocean corals, dated by another radiometric method - Uranium-Thorium dating - have also helped to extend the calibration curve beyond the age of the most ancient treering chronologies.

These techniques are made possible by sensitive electronic instruments developed in the late twentieth century. A computer program for radiocarbon age calibration.
