Radiocarbon dating is the most common technique used in ascertaining the age of archaeological and paleontological sites during the last 45,000 years.

More recently, accelerator mass spectrometry (AMS) has become widely available.With this technique, a sample’s C atoms are directly counted, meaning that samples can be much smaller.Recent developments in instrumentation have enabled radiocarbon dating to be conducted at archaeological sites rather than in a dedicated laboratory.Since Libby’s pioneering work, various factors have been identified that affect the atmospheric carbon reservoir.

Atmospheric testing of nuclear weapons in the late 1950s and early 1960s greatly increased the amount of radiocarbon in the atmosphere, so the decay rate of fourteen events per minute has more than doubled.

Therefore, radiocarbon dates are calculated to a “pre-bomb” age of 1950.
