The object is then set aflame and when it starts to emit fumes containing carbon dioxide, an accelerator mass spectrometer will be used to determine the amounts of carbon-14 decay.( A new study found that fossil fuel emissions could soon make radiocarbon dating techniques less accurate.The research, authored by Heather Graven of Imperial College London, was published in the Proceedings of the National Academy of Sciences and it presented simulations of carbon and carbon-14 dynamics in the future.look like they have the same age for radiocarbon dating," Heather Graven of Imperial College London, lead author of an article detailing the study, said.This is not the first time in modern history in which human activities are altering levels of carbon-14 in relics.
