Nuclear approach may help climate researchers pinpoint volcanic eruptions

There's gold in them thar rings. Tree rings that is, and Penn State researchers are using the Breazeale Nuclear Reactor to measure gold and link the rings to volcanic eruptions.
"Initially, when we began this work at Cornell University, we were simply looking to see what elements in tree rings could be measured using neutron activation analysis," says Dr. Kenan Unlu, professor of nuclear engineering and associate director for research of Penn State's Radiation Science and Engineering Center. "We can see a lot of elements, but it is easy to see the gold peak."
