The Beta-counting method detects the rate at which purified carbon decays. A rate of 7 decays/gram/minute would indicate an age of one half-life, or 5730 years old. 3.5 decays/gram/minute of carbon would be produced by a sample 11,460 years old.

In fact, the natural production of radiocarbon has varied as well.

This bomb radiocarbon has been gradually removed from the atmosphere by by natural processes, but the "bomb spike" can be shown through the dating by means such as comparing the bottle date and radiocarbon age of wines.

The surplus "bomb" radiocarbon is just one of the effects human have had on the ratio of C.

We describe the application of advanced radiocarbon strategies developed for situations such as caves with high carbon backgrounds. En este trabajo se describe la aplicación de técnicas de radiocarbono avanzadas, las cuales han sido desarrolladas para lugares como cuevas con un elevado fondo de carbón.

Using a low-temperature plasma oxidation system, we dated both the ancient paint and the biogenic rock coatings that cover the paint layers at Oxtotitlán. Fechamos tanto la pintura antigua como los recubrimientos biogénicos que cubren las capas de pintura utilizando un sistema de oxidación de plasma a temperatura baja.

Both methods rely on the ongoing production of radiocarbon in the upper atmosphere.
