Radioactive carbondating

The continual loss of energy by radioactive substances.

Disintegration of the nucleus by the emission of alpha, beta, or gamma rays eventually results in the complete loss of radioactivity.

Desmond Clark (1979) wrote that were it not for radiocarbon dating, "we would still be foundering in a sea of imprecisions sometime bred of inspired guesswork but more often of imaginative speculation" (Clark, 1979:7).

Writing of the European Upper Palaeolithic, Movius (1960) concluded that "time alone is the lens that can throw it into focus".

By measuring the ratio of the radio isotope to non-radioactive carbon, the amount of carbon-14 decay can be worked out, thereby giving an age for the specimen in question.

The problem, says Bronk Ramsey, is that tree rings provide a direct record that only goes as far back as about 14,000 years.

The radiocarbon method was developed by a team of scientists led by the late Professor Willard F.

Libby of the University of Chicago in immediate post-WW2 years.

Measured as the proportion of the atoms in a radionuclide that decompose per unit of time, usually stated as the half-life of that particular isotope.

called "neutrinoless double-beta decay" is observed, it would prove two things - one, that in certain circumstances more matter is in fact created than antimatter; and two, neutrinos (which are virtually massless particles produced during , probability distributions and transformations, discrete and continuous distributions, propagation of error, measuring radioactivity, Monte Carlo methods and applications in dosimetry, and regression analysis.

Various geologic, atmospheric and solar processes can influence atmospheric carbon-14 levels.
