Early estimates of C14’s half-life ranged from 1,000 to 25,000 years.

If the experimental data was correctly collected and interpreted, Libby’s assumption in estimating the original content is wrong.For example: “Nobody cites the many hundreds of C Carbon-14 is radioactive—therefore, it decays over time.It can be used as a dating tool because creatures and plants accumulate it during their lifetimes, and cease doing so when they die. If four essential facts are known, an age can be calculated with precision.This component of the formula is the most difficult to estimate due to the incalculable number of variables and unknowns.Contamination of some samples has been identified, leading scientists to take extra precautions in order to protect specimens.

The technique suggests that the specimen died about 5,730 years ago (one half-life).
