Carbon dating machine

One in many scientific fields such as hydrology, oceanography, archeology, and geology.

Many famous things have been radiocarbon dated such as the Dead Sea Scrolls and the Shroud of Turin.

Because the concentration of C14 is so minute, it is difficult to use conventional mass spectrometry.(2) A half-life is the time needed for half the initial number of radioactive nuclei to disintegrate.ten half-lives have past and the amount of 14C in the sample is so small that radiocarbon dating is no longer possible.Therefore, other methods such as OSL (Optically Stimulated Luminescence dating) or isotopes with longer half-lives researchers studying US bristle cone pine and German and Irish oaks discovered fluctuations in the C14 concentration.Measurements of the Libby half-life showed that Libby was about .3% too low.
