Subject: Is it possible to dislodge the radioactive stuff from a smoke detector?

A funny thing happened to me when I was at a cafe.  I noticed that the person who 
was handling my food was taking apart a smoke detector, for some reason or other, 
maybe curiosity.  I have noticed before that smoke detectors have a label that 
says radioactive.  I am wondering if it is possible to remove the radioactive 
substance somehow and contaminate objects that you touch, including food.  I am 
concerned because this guy obviously didn't know what he was doing!  I should 
have asked him about it but I didn't really think about the consequences until 
later.
