americium-241

Dmytro Melnychuk, rector of the national university, said: Strontium-90, plutonium, and americium-241 are all extremely susceptible to upward atmospheric migration and dispersal via heat from fires.

He explains in Nature that he has taken the americium-241 from a smoke detector, and coupled it to an emerald stone.

In particular, 241Pu (half-life 14 years) decays to americium-241 (241Am), a strong gamma ray emitter, giving rise to a potential occupational health hazard if separated plutonium over five years old is used in a normal MOX plant.

The first home smoke detector, patented by Randolph Smith and Kenneth House in 1969, didn't qualify, but most of today's models contain a small piece of americium-241, which emits radioactive particles that generate an electric current.

Any health risk associated with the use of the small americium-241 sources in the smoke detectors was negligible.
