In this episode, Jason Church speaks with Curtis Deselles, an intern with the Materials Research program at NCPTT, discusses the use of eddy currents and eddy current technology in conservation science. Mr. Deselles has built several eddy current analyzers, custom software, and presented on this topic at a non-destructive conference in St. Louis.

NCPTT has been using eddy current technology in preservation and will be bringing this tool to the iPhone platform in 2010. Download Episode 8 as an mp3 or subscribe via iTunes.

Some natural science specimens and ethnographic artifacts in museums were historically treated with arsenic and mercury salts. This has created an environmental concern for museum workers and the public who may be exposed to these toxins. In addition, museums are frequently being asked to return sacred objects under the Native American Graves Protection and Repatriation Act (NAGPRA).

NCPTT hosted a MayDay Event “Preparing You for the Next Disaster” in Natchitoches, La.
