выделить полоний из золота ПМСМ по силам студенту-химику
тут пишут, что полоний внедрен в золотую фольгу с дополнительным золотым напылением сверху, что делает его нерастворимым в воде. там они еще обсуждают опасность для пожарных , тушащих склад щеток, но злонамеренных добытчиков явно не предуматривают.

The following description from NUREG-1717 describes the fabrication of the sources for the newer static eliminators: "A technology similar to that used in making 241Am sources for smoke detectors is currently being used to make the 210Po sources. The 210Po sources made of ceramic microspheres are no longer used in the manufacturing of static elimination devices in the United States. The 210Po sources made in the United States have a silver backing plate covered by a thin gold foil and a second composite foil of gold and 210Po. These foils are locked together by a pressure weld metallurgy process. The composite foil of gold and 210Po is then gold plated to provide an encapsulated source that is insoluble and inert in most chemicals. The solid metal source is mechanically fastened within a rigid housing and steps are taken to prevent disassembly of the source housing."
