I'm interested in this question as well.  At our small university, 
I'm the only regular user of radioisotopes (and the RSO as well).  I 
share lab space with another PI who doesn't use isotopes.  Several 
students do work in the room, and housekeeping personnel empty 
wastebaskets.  Since I only use small quantities of soft beta 
emitters, my solution was to declare my lab a "controlled area".  For 
me, this means the door stays locked when no one is present, and only 
people signing a release form saying they won't mess with anything 
on/around radioactive work areas are allowed in without supervission. 
 A sign on the door states these things.
    This practice is described in our license renewal (agreement 
state) application.  I have not heard yet whether the authorities like 
or dislike this. In my case, I'm trying to use the ambiguity to 
create a safe but easily workable solution.  Other opinions?
