Recent debate regarding the potential carcinogenic consequences upon the health of workers handling carbon nanotubes in both research and manufacturing environments has raised awareness of the presence of these nanostructures in modern life.  This presentation describes the presence and characterization of nanotubes found in irradiated wine corks from different manufacturers, radiated at 5 kGy, 10 kGy, and 15 kGy.  The respective dosages of radiation appear to influence the number of nanotubes present on the cork's surface.  A thorough characterization of the nanotubes was conducted by means of energy-dispersive X-ray spectroscopy (EDX), Raman spectroscopy, scanning electron microscopy (SEM), and transmission electron microscopy (TEM).
