At the City of Austin's home chem facility (at least four years ago when I worked there) we considered smoke detectors radioactive waste. You might check with the manufacturer to see if they will take them back. If you want to see what the current manager of the home chem facility is doing with them call Tony Davee, 512-974-4345.
