[ RadSafe ] Question on 10CFR 20

Hi Radsafers,

I have a question regarding 10CFR Part 20 - Standards for Protection 
Against Radiation. Specifically the section dealing with dose limits 
for members of the public. I'm quoting part of it:

" 20.1301 Dose limits for individual members of the public.
a) Each licensee shall conduct operations so that --

(1) The total effective dose equivalent to individual members of the 
public from the licensed operation does not exceed 0.1 rem (1 mSv) in 
a year... "(SNIP)

My question is: is this a limit to be complied with by each nuclear 
installation (i.e. reactor, plant, etc) independently? or else, in 
case there is more than one facility in a given area, should the 1 
mSv/year limit be the summation of the contributions from all of 
them? FWIW, the latter case is the regulatory concept applicable in Argentina.

I'll appreciate any insights on this subject.
