Learning Outcomes After viewing the video on carbon dating, use your newfound knowledge to: Calibration of radiocarbon dates.
Naturally occurring carbon is made up of 3 isotopes: Carbon dioxide in the atmosphere contains a constant amount of carbon, and as long as an organism is living, the amount of carbon inside it is the same as the atmosphere. High School Physical Science: Please do not block ads on this website. Soon after the publication of Libby's paper in Science , universities around the world began establishing radiocarbon-dating laboratories, and by the end of the s there were more than 20 active 14 C research laboratories. It frequently happens that a sample for radiocarbon dating can be taken directly from the object of interest, but there are also many cases where this is not possible.
