Re: posting requirements

Two points are in order.

1.  There is no requirement to post restricted areas.  Just lock the 
door to prevent access to the radioactive material and the area is, 
by definition, a restricted area.

2.  The  CRAM posting is required for the presence of 10x Appendix C 
quantities.  So if I have a researcher using 5 mCi of P-33 (5x 
Appendix C) and I label the door, have I mislead workers and members 
of the public?  If a researcher conducts an experiment once a month 
should the room be posted during the experiment, and unposted after 
the waste is removed?  I don't believe (and I expect that no one out 
there believes) that we should waste our time posting and unposting 
facilities as the activity levels rise above and below the posting 

While I agree that using the radiation symbol for non radioactive 
work is "blatantly misleading" and should be discouraged, keep 
in mind that this could be considered an extension of accepted 
practices depending on one's perspective.
