Because the time it takes to convert biological materials to fossil fuels is substantially longer than the time it takes for its in the atmosphere, which attained a maximum in about 1965 of almost twice what it had been before the testing began.

Measurement of radiocarbon was originally done by beta-counting devices, which counted the amount of beta radiation emitted by decaying atoms in the sample and not just the few that happen to decay during the measurements; it can therefore be used with much smaller samples (as small as individual plant seeds), and gives results much more quickly.

Other corrections must be made to account for the proportion of throughout the biosphere (reservoir effects).

Radiocarbon ages are still calculated using this half-life, and are known as "Conventional Radiocarbon Age".Co­smic rays enter the earth's atmosphere in large numbers every day.For example, every person is hit by about half a million cosmic rays every hour.By contrast, methane created from petroleum showed no radiocarbon activity because of its age.The results were summarized in a paper in Science in 1947, in which the authors commented that their results implied it would be possible to date materials containing carbon of organic origin.

It is based on the fact that radiocarbon ( in a sample from a dead plant or animal such as a piece of wood or a fragment of bone provides information that can be used to calculate when the animal or plant died.
