Such small uncertainties are no reason to dismiss radiometric dating. All of the dating schemes work from knowing the present abundances of the parent and daughter isotopes. Claim: There are only a few different carbon dating error margin methods.
Response: [Wiens' article] has listed and discussed a number of different radiometric dating methods and has also briefly described a number of non-radiometric dating methods. Well over forty different radiometric dating methods are in use, and a number of non-radiogenic methods not even mentioned here. Claim: A young-Earth research group reported that they sent a rock erupted in from Mount Saint Helens volcano to a dating lab and got back a potassium-argon age of several million years.
Carbon 14 Dating margin for error
Radiocarbon helps date ancient objects-but it's not perfect The result is then calibrated and presented along with a margin of error. In last Tuesday's lecture, radiocarbon dating was covered briefly. It is an essential technology that is heavily involved in archaeology and. Scientists use Carbon dating for telling the age of an old object, whose origin and If we do not ignore them, and I think that 12% is a very large error margin.
