Target preparation for radiocarbon dating by tandem

Radiocarbon dating, also known as carbon-14 dating, is a radioactive decay-based method for determining the age of organic remains that lived within the past 50,000 years. Most carbon-14 is created from nitrogen-14 in the earth’s upper atmosphere as a consequence of cosmic ray bombardment.

What is AMS? (Accelerator Mass Spectrometry)

Accelerator mass spectrometry (AMS) has been applied to a number of other long‐lived radioisotopes during the past 10–15 years and has been found to be important in research on human biochemistry. Hydrogen is used together with carbon for organic tracing in vivo with molecules labeled with 3 H (T 1/2 = 12.33 y) and 14 C.
