There is a quantitative relationship between the decay of 14C and the production of a beta particle. That is, the probability of decay for an atom of 14C in a discrete sample is constant, thereby requiring the application of statistical methods for the analysis of counting data.

Plants and animals which utilise carbon in biological foodchains take up 14C during their lifetimes.

By measuring the C14 concentration or residual radioactivity of a sample whose age is not known, it is possible to obtain the countrate or number of decay events per gram of Carbon.

By comparing this with modern levels of activity (1890 wood corrected for decay to 1950 AD) and using the measured half-life it becomes possible to calculate a date for the death of the sample.

Nyerup's words illustrate poignantly the critical power and importance of dating; to order time.

Radiocarbon dating has been one of the most significant discoveries in 20th century science.
