RE: smoke detectors
It might be prudent to record the manufacturer, model, serial number and
activity of each unit as well as the number of units discarded at any one
time. NRC final ruling last year on generally licensed material (such as
sealed sources) suggests treating generally licensed material more like
specifically licensed material if you are a licensed entity. We operate
under a broad scope NRC license and follow advice provided by consultants to
keep such records and limit disposal to 10 units or less at any one time.
The amount of activity per unit is another consideration. If greater than 1
microcurie per unit, disposal as rad waste may be appropriate. Homeowners
and unlicensed institutions are free from such measures.
Opinions are fallible

Just FYI -
In a Feb. 11, 1986 memorandum from Richard E. Cunningham, then Director of
NRC's Division of Fuel Cycle and Material Safety, NMSS, the NRC's position
was that secondary distributors and consumers may dispose of domestically
produced smoke detectors, even in bulk, as ordinary trash.
