WebRadiocarbon dating is a radiometric dating method that uses ( 14 C) to determine the age of carbonaceous materials up to about 60,000 years old. The technique was developed by Willard Libby and his colleagues in 1949 [10] during his tenure as a professor at the University of Chicago. WebIf C-14 is used to date an object, the object must have died within how many years? Solution: In decimal form, 0.20% is 0.0020. This is the amount remaining. (1/2)n= 0.0020 n log 0.5 = log 0.0020 n = 8.9658 --- this is how many half-lives have elapsed (5730 yr) (8.9658) = 51374 yr
