Can radiocarbon dating

The 14C formed is rapidly oxidised to 14CO2 and enters the earth's plant and animal lifeways through photosynthesis and the food chain.The rapidity of the dispersal of C14 into the atmosphere has been demonstrated by measurements of radioactive carbon produced from thermonuclear bomb testing.Herein lies the true advantage of the radiocarbon method, it is able to be uniformly applied throughout the world.Included below is an impressive list of some of the types of carbonaceous samples that have been commonly radiocarbon dated in the years since the inception of the method: The historical perspective on the development of radiocarbon dating is well outlined in Taylor's (1987) book "Radiocarbon Dating: An archaeological perspective".Nyerup's words illustrate poignantly the critical power and importance of dating; to order time.

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.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.It follows from this that any material which is composed of carbon may be dated.Libby later received the Nobel Prize in Chemistry in 1960: (From Taylor, 1987).Today, there are over 130 radiocarbon dating laboratories around the world producing radiocarbon assays for the scientific community.
