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.
A smoke detector is a device that senses smoke, typically as an indicator of fire. Commercial security devices issue a signal to a fire alarm control panel as part of a fire alarm system, while household detectors, known as smoke alarms, generally issue a local audible or visual alarm from the detector itself.s 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.
