The counters work by detecting flashes of light caused by the beta particles emitted by 14 C as they interact with a fluorescing agent added to the benzene. The dating framework provided by radiocarbon led to a change in the prevailing view of how innovations spread through prehistoric Europe. This fossil fuel effect also known as the Suess effect, after Hans Suess, who first reported it in would only amount to a reduction of 0. So you might get a question like, I start with, oh I don't know, let's say I start with 80 grams of something with, let's just call it x, and it has a half-life of two years. So I wrote a decay reaction right here, where you have carbon But let me ask you a question.
The other common technology used for measuring 14 C activity is liquid scintillation counting, which was invented inbut which had to wait until the early s, when efficient methods of benzene synthesis were developed, to become competitive with gas counting; after liquid counters became the more common technology choice for newly constructed dating laboratories.
