∙ 13y agoAccording to NFPA research, 96 percent of US homes have at least one smoke alarm. Unfortunately, at least 23 percent of them are useless because they do not have working batteries.
Homes with smoke alarms that don't work now outnumber homes that don't have any smoke alarm at all.
Two thirds of deaths in fires in the home occur in homes without working alarms.

Americium-241 ionizes the air inside a smoke detector, making a small change in voltage when smoke is present.
