Smoke detectors are the most common consumer product that uses nuclear technology. They work by putting a source of alpha radiation, usually Americium-241, near an ion detector.hen there is a certain concentration of smoke in the air, the charge drops, and the electronics in the detector sound an alert. This design allows smoke detectors to work for a long time, because Americium-241 has a half-life of 458 years. Source: Teaching Advanced Physics.
As of November 2013 it is estimated that smoke detectors are installed in 93 percent of US homes and 85 percent of UK homes. Roughly 30 percent of these alarms are estimated to not work, due to aging, removal of batteries, or failure of owners to replace dead batteries.hen these batteries run down, the smoke detector becomes inactive. Most smoke detectors will signal a low-battery condition. The alarm may chirp at intervals if the battery is low, though if there is more than one unit within earshot, it can be hard to locate.
