Dating human skeletal remains

Currently, there are no reliable methods to resolve PMI, the determination of which relies almost exclusively on the experience of the investigating expert.

For instance, Pb dating was added to narrow the PMI interval.

In contrast, from 1955 to 1963, atmospheric radiocarbon levels almost doubled.

Since then they have been dropping back toward natural levels.

We also found that adding the activity of (210)Po, a proxy for naturally occurring (210)Pb incorporated through ingestion, to the (90)Sr dating increases the reliability of the PMI value.

Our results also show that trabecular bone is subject to both (90)Sr and (210)Po diagenesis.
