Archaeology and other human sciences use radiocarbon dating to prove or disprove theories. Over the years, carbon 14 dating has also found applications in geology, hydrology, geophysics, atmospheric science, oceanography, paleoclimatology and even biomedicine.
What machines use carbon dating?
Accelerator Mass Spectrometer In the early years of radiocarbon dating a products decay was measured, but this required huge samples (e.g. half a human femur). Many labs now use an Accelerator Mass Spectrometer (AMS), a machine that can detect and measure the presence of different isotopes, to count the individual 14C atoms in a sample.
