A mathematical explanation of carbon dating and half life Free no charge chat lines in toronto
The radiocarbon age of a certain sample of unknown age can be determined by measuring its carbon 14 content and comparing the result to the carbon 14 activity in modern and background samples.The principal modern standard used by radiocarbon dating labs was the Oxalic Acid I obtained from the National Institute of Standards and Technology in Maryland. Around 95% of the radiocarbon activity of Oxalic Acid I is equal to the measured radiocarbon activity of the absolute radiocarbon standard—a wood in 1890 unaffected by fossil fuel effects.

In this method, the sample is in liquid form and a scintillator is added.By knowing how much carbon 14 is left in a sample, the age of the organism when it died can be known.It must be noted though that radiocarbon dating results indicate when the organism was alive but not when a material from that organism was used.American Chemical Society National Historic Chemical Landmarks.
