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?

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 ...

Chinese scientists are leveraging americium, which has usually been written ... or challenging environments where traditional ...

Americium, in this case ... miniature sensors in remote or challenging environments where traditional power sources are ...

The alpha particles flowing from the americium (it's a better alpha source than radium) pass through a small compartment where they ionize the air, allowing a tiny electrical current to cross the ...

Perpetual Atomics is excited to announce this collaboration, which will enable the processing of americium into sealed sources for use in radioisotope power systems, including radioisotope heater ...
