Idaho carbon dating
I use scintillant every day in my own work to detect H-tagged hormones.
I now understand why fossil fuels are not routinely used in radiometric dating! Gove and his colleagues are currently trying to improve AMS technology to be able to identify certain fossil fuels that have extremely low C levels, and then those oils would be the ones used in the neutrino detectors.
