Radio dating accuracy

Radiocarbon dating is simply a measure of the level of C isotopes in the atmosphere can vary.This is why calibration against objects whose age is known is required (14).When the half-life was corrected in 1950, the year was taken as a base date from which to calculate all resulting dates.Therefore, any expression of “before present” will mean “before 1950”.

By applying magnetic and electrical fields, the mass of these ions is measured and the accelerator is used to remove ions that might contaminate the dating.It also has some applications in geology; its importance in dating organic materials cannot be underestimated enough.In 1979, Desmond Clark said of the method “we would still be foundering in a sea of imprecisions sometime bred of inspired guesswork but more often of imaginative speculation” (3).The sample passes through several accelerators in order to remove as many atoms as possible until the C pass into the detector.These latter atoms are used as part of the calibration process to measure the relative number of isotopes (9).
