Hazards of carbon dating

The change in global radiocarbon levels brought about by human activities necessitated the use of a reference standard for carbon 14 dating. National Bureau of Standards had been adopted as standard for radiocarbon dating.

Radiocarbon dating needed an organic material that was not contaminated with carbon 14 from fossil fuel burning or nuclear weapons testing. Its radiocarbon content was theoretically the same as a wood sample grown in AD 1950, the zero point of the radiocarbon timescale used in quoting carbon dating results.

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.

According to literature, the excess carbon 14 produced during nuclear weapons testing has already decreased due in part to the global carbon exchange cycle.

The level of bomb carbon was about 100% above normal levels between 19.

The level of bomb carbon in the northern hemisphere reached a peak in 1963, and in the southern hemisphere around 1965.
