While Kathleen makes some excellent points, I'd like to add that if 
one of the objectives of monitoring, beyond determining  the "total" 
dose, is to identify where the maximum doses are coming from, using 
that knowledge, permitting actions to be taken to reduce what is 
considered unnecessary exposure, then identifying dose by location is 
a useful tool. As far as multiple badges, 10CFR20, as well as state 
regulations, requires that a facility, when an individual's exposure 
has the potential to exceed 10% of the limit requiring monitoring, 
that the individual's current years, as well as lifetime dose, be 
determined. This only requires a written statement from the 
individual. Personally, the latest regulations leave a lot to be 
desired, since each facility has to demonstrate that the individual 
will never exceed the threshold for monitoring, thus, never having to 
obtain the statement from the individual. In this context, a person 
could very well exceed the regulatory limits, legally.
