The half life of Carbon 14 is 5,730 years. So all it would be able to do is tell you the person is between 0 and 5,730 anyway right?
That wouldn’t help solve these cases.
That wouldn’t help solve these cases.
That said, you generally have error boundaries spanning multiple decades and it measures since time of death (when new carbon stops being integrated into the body) not time of birth, so it would not be useful for this.
That said, the error bars are simply too large to do anything reasonable for dates prior to 1955. The difference between 80 years and 110 years is 98.7% vs. 99.0% of the original C14 concentration... and while you may be able to get a very precise measurement of the remaining C14 you also need to very precisely know the baseline from that era to determine the percentage. Thus typical radiocarbon error bars are at least ±60 years.
