[ RadSafe ] Classification of areas

[WILLIAM LIPTON]

"Are there any further requirements to be met by 
each type of area..."
 
What you quoted does not specify requirements.  It is merely a classification system.  As a start, read the rest of 10 CFR 20, the associated USNRC Regulatory Guides, and other interpretive material, such as NUREG 1736, " Consolidated Guidance: 10 CFR Part 20 - Standards for Protection Against Radiation."  You should be consulting a professional health physicist.

Subject: [ RadSafe ] Classification of areas

Hi Radsafers,

I've seen in 10 CFR 20.1003 a classification for 
areas in nuclear facilities, part of which I'm quoting below:

·        Controlled area means an area, outside 
of a restricted area but inside the site 
boundary, access to which can be limited by the licensee for any reason.
...
·        Restricted area means an area, access 
to which is limited by the licensee for the 
purpose of protecting individuals against undue 
risks from exposure to radiation and radioactive 
materials. Restricted area does not include areas 
used as residential quarters, but separate rooms 
in a residential building may be set apart as a restricted area.
...
·        Unrestricted area means an area, access 
to which is neither limited nor controlled by the licensee.

Are there any further requirements to be met by 
each type of area, like the need for special work 
procedures, dose limits, warning signals, and so 
on? If so, in which standards or regulatory 
guides or documents in general can I find them?

I'll appreciate your inputs.
