The publication of radiocarbon dates rests almost totally with the submitter of the material.In many instances, researchers have in recent decades, neglected to publish relevant data describing the sample, laboratory and reference numbers, provenance and reservoir correction details.These may be involved with uncertain reservoir corrections, especially for shell dates, corrections for isotopic fractionation and failure to specify whether the old or new half-life was used.

The older a sample is, the less (the period of time after which half of a given sample will have decayed) is about 5,730 years, the oldest dates that can be reliably measured by this process date to around 50,000 years ago, although special preparation methods occasionally permit accurate analysis of older samples.

Founded in 1979, Beta Analytic has provided radiocarbon dating services to universities, government agencies, and private institutions worldwide through its offices and representatives in London, UK; Nagoya, Japan; Beijing, China; New Delhi, India; Sao Paulo, Brazil; and now North Sydney, Australia.

Beta Analytic also provides other testing services based on radiocarbon analysis – ASTM D6866, CEN 15747, and EN 15440 testing services.

Such practices seriously undermine the value of radiocarbon dates because they lack a meaningful context.

Some of the problems associated with interpreting the corpus of radiocarbon data obtained thus far concern variation in reporting.

“Starting February 1, all our archaeology and geology clients in Australia, New Zealand, and Southeast Asia can now enjoy a more convenient way to submit their samples to us for radiocarbon analysis.

As with our other forwarding facilities, samples sent to the North Sydney office are sent overnight through expedited courier services at the company’s expense,” Beta Analytic director Thierry Tamers announces.

The method was developed by Willard Libby in the late 1940s and soon became a standard tool for archaeologists.

The idea behind radiocarbon dating is straightforward, but years of work were required to develop the technique to the point where accurate dates could be obtained.

Research has been ongoing since the 1960s to determine what the proportion of in the atmosphere has been over the past fifty thousand years.
