Bruce,

	A partial answer to some of your questions.  I quote from 
Nureg/CR-6204, "Questions and Answers Based on Revised 10 CFR Part 20." 
p. 4:

Start of quote-----

By definition, and with the exceptions given in the definitions of 
"occupational dose," any dose received by any individual in a 
"restricted area" is an "occupational dose."  No one in a restricted 
area is a "member of the public."  Outside "restricted areas" (i.e. in 
"controlled areas" or in "unrestricted areas"), whether the dose to an 
individual is an "occupational dose" or a "public dose" depends on 
whether the dose received by the individual is (as specified in the 
definition of "occupational dose") a dose received "in the course of 
employment in which the individual's assigned duties involve exposure to 
radiation and to radioactive material from licensed and unlicensed 
sources of radiation, whether in the possession fo the licensee or other 
person."  In other words, outside "restricted areas," whether the dose 
to an individual is an "occupational dose" or a "public dose" (and 
whether the occupational dose limits or the public dose limits apply to 
the individual) depends on what the individual is doing and NOT 
(emphasis in original) on what area (controlled or unrestricted area) 
the individual is in when the dose is received.

I think that may address what you were questioning.  Hope it helps.
