The C-14 method cannot be used on material more than about 50,000 years old because of this short half-life.Other isotopes are used by geologists to date older material.Even though radiocarbon dating is a pretty well known technique not all archaeologists that have organic samples are able to do it, or perhaps more importantly, the funds to do it. Radiocarbon dating methods have really improved over the decades.It can cost over 0 to run these kinds of special scientific tests so sometimes archaeologists need to rely on other dating techniques instead. In the 1940s physicists need really large samples to test radiocarbon—they would use a Geiger counter to literally count the rate of decay and it wasn’t very accurate.

Upon death, the isotope begins to decay and after 5730±40 years half of it is gone.To better serve its archaeology and geology clients in South Asia, particularly those in India, ISO/IEC 17005-accredited radiocarbon dating lab Beta Analytic Inc. The office accepts samples throughout the region and sends them overnight to Beta Analytic headquarters in Miami, Florida, for radiocarbon analysis.The lab provides commercial radiocarbon dating services with faster turnaround times than most university labs around the world.Since tree rings provide an annual calendar, and some trees live for thousands of years, by C-14 dating the rings themselves one could correct the radiocarbon dates and calibrate the differences. should refer to the year the method was recognized, 1950.
