It’s widely known that a smoke detector is a good ionizing radiation source, as they contain a small amount of americium-241, a side product of nuclear reactors. But what about other sources?

One example of a use of alpha radiation is in smoke detectors. A source of alpha radiation is used because the range is very low and alpha radiation has a very high ionising power.

The photodiode is actually sensitive enough to detect the small amounts of gamma radiation produced from a smoke alarm americium source, and also registers [Alan]’s other more powerful ...

To measure radiation levels, a Geiger counter works ... and you can also find radioactivity in your smoke detectors, and those can save lives," he told Newsweek. With more than 590 comments ...

This supplement is an update of Technical Report Series No. 318, Compendium of Neutron Spectra and Detector Responses for Radiation Protection Purposes (1990), that takes into account the major ...
