Carbon 14 dating procedure

To determine year of birth, the researchers focused on tooth enamel.

I understand that the method can provide dating up to ca.

50,000 years into the past, but I'm interested in the other end of the time range: is there a point in time when younger (recent) specimens can no longer be dated with accepted accuracy?

I have read sources that place this limit anywhere between 50 and 500 years.

I have read that this difficulty in the young-sample range is due to the fact that not enough material has been depleted to calculate accurately.

) at about the same rate as the radioactive decay rate, this leads to an ambiguity in the age determination and then there would be a 50 year uncertainty in any radio-carbon age from about that time, even with very precise measurements, but you could reasonably confirm that something was at least 350 years old.
