The Preservation Directorate of the Library of Congress announces
the 29th lecture in its series on "Topics in Preservation Science
(TOPS)," Wednesday, December 12, 2007, from 1:30 - 2:30 PM.

Dr. Greg Hodgins, Assistant Research Scientist and Assistant
Professor of Anthropology at the National Science Foundation

"Arizona Accelerator Mass Spectrometry (NSF-Arizona AMS) Laboratory,
will present "AMS Radiocarbon Dating of Museum Objects."

The NFS-Arizona AMS Laboratory is the premier center for
archaeological radiocarbon dating in the United States, having
performed measurements on the Shroud of Turin, the Dead Sea Scrolls,
the Vinland Map, and the Gospel of Judas.  Dr. Hodgins will discuss
how radiocarbon dating is performed using AMS, including
conventional applications such as the dating of papyrus and
parchment documents and newer applications that permit 20th Century
forgeries of art and artifacts purportedly created before 1955 to be
determined based on the detection of atomic bomb-derived 14C.

The Topics in Preservation Science lectures are free and open to the
public. For more information about this series, which is continually
expanded and updated, see
