Recent experiments at the U.S. Navy San Diego SPAWAR Systems Center have demonstrated nuclear effects with palladium co-deposition cathodes subjected to magnetic or high voltage fields. CR-39 is used to detect high energy particles. It is placed in close proximity to the cathode because the particles do not travel far. These experiments appear to be highly repeatable. See:
