Actually, you need to move the decimal point over a couple of places: the t1/2 of Am-241 is ~ 430 y. Otherwise, it sounds like good advice to me.

Shane, your first point of contact should be your local (municipal
and state) authorities. Some municipalities have established
recycling depots for smoke detectors. Provide the date of manufacture
re. the Am-241 model (t 1/2 = 4.33 years, so disposal may be fairly
straight forward and inexpensive). Ra-226 should NOT be directed to
any municipal waste site.
