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.
Smoke detectors alert people to fires. Smoke from the fire is detected by the device, which then gives off an alarm. One type of smoke detector uses americium-241, a source of alpha radiation, to detect smoke. The diagram shows how it looks inside.The alpha radiation ionises the air particles inside the smoke detector.moke detectors alert people to fires.
