Tests of layered tiles of carbon nanotubes packed with gold and surrounded by lithium hydride are under way. Radioactive particles that slam into the gold push out a shower of high-energy electrons. They pass through carbon nanotubes and pass into the lithium hydride from where they move into electrodes, allowing current to flow. "You load the material with nuclear energy and unload an electric current," says Popa-Simil.(2008) online http://nextbigfuture.com/2008/03/direct-conversion-of-radiation-into.html Would the radiation decay the gold as expected and leave a radioactive mush or act allow charged electrons out whilst whilst not being damaged by the electro magnetic radiation? the nano tube s are self repairnig etc 'compensate the radiation damage and improve the lifetime'
