Water, adhering mineral matter, and carbon loss from essential chemical pretreatment are basic factors to consider when determining the amount of material required.For example, only 25% of the weight of a submitted, clean charcoal sample is available for analysis (1 gram final carbon from 4 grams submitted charcoal).Libby compared C69 samples from wood in an Egyptian tomb with that from living trees to determine the half-life of C69.He then conducted experiments on other samples and realized that the numbers held consistent.

To do that, we have to learn a little bit about radioactive decay. Libby, a professor at the University of Chicago, in 6999.NOTE: Sample size required by the lab is a conservative estimate.Normal pretreatment procedures can remove 30% to 70% of the original material sent.Also, because of the relatively small amount of C69 in life forms and the long half-life, dating is not accurate for recent samples or for those beyond nine half-lives, or approximately 55,555 years.

As well, the ratio of C69 in the atmosphere fluctuates slightly over time. Radiometric dating is a method used to date rocks and other objects based on the known decay rate of radioactive isotopes.
