Nuclear-Powered Cardiac Pacemakers
Pacemakers are used to stimulate a regular heartbeat when the body’s natural electrical pacing system is irregular or not transmitting properly. Over the years, various power sources have been used for pacemakers, including a radioactive material called plutonium-238. There are still a number of people in the U.S. who have nuclear powered pacemakers, which need to be disposed of properly upon removal.
What to look for:
Unfortunately, not all pacemakers look the same. Different indicators may be used to determine if a pacemaker is nuclear-powered, or non-nuclear. Observe the markings on the pacemaker body. If you see the word “Nuclear” or “Curies” – or if you see the radiation symbol, or the abbreviation “Pu-238,” the device battery does indeed contain radioactive material. If none of these markings occur, chances are the pacemaker is non-nuclear and simply contains a chemical-type battery.
Nuclear-powered cardiac pacemakers were manufactured by many companies. If one of the following manufacturer names appears on the device, it may contain radioactive material: ARCO (Perma-grain), Medtronic (Laurens-Alcatel), Gulf General Atomic, Cordis (Telektronic, Accuffix), American Optical, Biocontrol Technology (Coratomic), and Medical Devices, Inc (MDI).
What to do if you find a nuclear-powered cardiac pacemaker:
Upon explantation and sterilization (do not autoclave), please observe the markings on the pacemaker. If any of the markings indicate that the device contains radioactive material, please contact OSRP for shipping and disposal instructions:
