Depends on the household.  

Mostly, I'd think of tritium/promethium watches, compasses and "procured"
airplane nav devices, lantern mantles (thorium impregnated), and americium
smoke detectors.

This is, actually, the list of exempt sources in the Colorado Regulations.

Then there's radon and progeny in the basement, and all the fallout on the
tobacco leaves in cigarettes.  And the infamous K-40 in bananas.

Hope this helps.
