Thankyou Wayne. That is a really good public service announcement. I'd never considered the real reason behind that chirping and always just put batteries in. Looking up smoke detectors says the two main radioactive elements are americium and neptunium. Gee, I don't know my periodic table very well. One thing I remember from my radiography days is that bananas are radioactive. Due to potassium. You get more radiation every day though in the natural environment.
Time to go to the hardware store.
