[ RadSafe ] RE: Public Opinion & Nuclear Project

Don,
You may be right about what is allowable.  I know that
a license is to use signs and label to identify
radioactive sources and areas.  Our thought that using
them inappropriately was "misleading" to our
surveyors. I sounds like you are doing what we do
regarding the use of labels.

Yes, it is trefoil, (a symbol in the design of a
trifoliate leaf).  Another example of why your spell
checker should be left on.  The NRC calls it a
three-bladed design
