Establishing the age at death of individuals is an important step in their identification and can be done with high precision up to adolescence by analysis of dentition, but it is more difficult in adults. Here we show that the amount of radiocarbon present in tooth enamel as a result of nuclear bomb testing during 1955-63 is a remarkably accurate indicator of when a person was born. Age is determined to within 1.6 years, whereas the commonly used morphological evaluation of skeletal remains and tooth wear is sensitive to within 5-10 years in adults.
确定个体的死亡年龄是身份识别中的重要一步，通过牙列分析，在青春期之前可以高精度地完成，但在成年人中则更具难度。我们在此表明，1955年至1963年核弹试验导致牙釉质中存在的放射性碳含量是一个非常准确的出生时间指标。年龄可确定在1.6年以内，而常用的骨骼遗骸形态评估和牙齿磨损评估在成年人中对年龄的敏感度在5至10年以内。
