Sure does.  When I worked at the VA, we used to leave the adjacent room
vacant.  We also had to use shields occasionally for the first day post
admin..  Oh, and the limit is 2 mrem in any hour, which is different than 2
mr/hr (dose compared to dose rate).  This may or may not be important
depending on the size of the room, the amount of time the patient is near a
boundary, etc..
