Chad Orzel, assistant professor of physics, gave a talk at the Low
Radioactivity Techniques Workshop (LRT2004) in Sudbury, Ontario,
on Dec. 13. This was an international workshop of people working on
astrophysical detectors and other projects requiring extremely low levels of
radioactivity, with participants from several countries, including the U.S., Canada,
Germany, Italy, Japan
and South Korea.
He was the only speaker from a small liberal arts college; most were from large
research universities or national labs. His talk was on the use of Atom Trap
Trace Analysis for measuring radioactive krypton background levels in other
gases. The work is important for a number of large astrophysical detectors
under construction. More information is available at http://lrt2004.snolab.ca.
