I'm collecting old fire-detektors 
But I'm wondering how much Americium each detector contains? I borrowed a geiger-counter and the activity was about 40 kBq om each detector, when
I have picked out the radioactive source. But I still doesn't know how much of the radioactive piece that is pure Americium. Anyone who knows?

A smoke detector contains 0.26 micrograms of americium-241. Source: Carey Sublettes' Nuclear FAQ

Thanks!
That wasn't much! But I expected it was a very, very small amount.
