- Everyday life
An ionisation smoke alarm contains a sealed americium-241 source of well under a microgram. It is the most widespread domestic use of a synthetic radioisotope, and disposal rules differ from ordinary waste in most jurisdictions.
- Science
Americium-241 ionises air in an ionisation-chamber smoke alarm. Millions of households contain a small sealed source, which is the most widespread domestic use of a synthetic radioisotope.
- Geography
+241 reaches Gabon, in the 24x central African range. Gabon is around 88 percent forested and was the first African country paid for reducing deforestation under a results-based agreement.
