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 ...

A multi-institutional team of physicists and engineers has developed a laser-based radiation detection system that operates ...

Although the length of the laboratory used for the proof-of-principle experiment limited detection to a maximum of 10 meters from the radiation source, the researchers expect that the method is ...

Inside your smoke detector, there’s a small Americium-241 radiation source that’s a byproduct of nuclear fuel. It emits alpha particles, which you can think of as little bullets. These little ...

Additionally, we are exposed to varying amounts of radiation from sources such as dental and other medical X-rays, industrial uses of nuclear techniques and other consumer products such as luminized ...

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.
