You may not be aware, but some certain symbols are federally regulated
(mandated, actually). The aspect ratios, colors, and other characteristics
appear in federal regulations (and many state regulations as well). The
radiation symbol is one of them (reference is below), and the US flag, and
probably others (the 4-diamond hazard symbol?). If you want this clipart to be
useful, you should remove any special effects from it. Otherwise you should
remove it completely from your clipart collection. Obviously, there is no
copyright associated with something that appears in legislation, but people
can get themselves into trouble this way.

Which federal regulations? Architetto Francesco Rollandin lives in Italy, which
AFAIK is not federative country.
I don't think anyone claim this is an official symbol.
For flags we usually strive to make them as accurate as possible.
BTW, file in question is
I am tempted to close this as INVALID...
Reporter, feel free to submit a new nuclear symbol with whatever ratio, colors,
and other characteristics you think are correct.
This is opinion. If interested, please make a up a tag for official and government name and then promote this through our project. Closing, and thanks
