Ultraviolet covers much more of the spectrum than visible light does,
beginning right above the wavelengths we can see and extending into the
X-ray range as you can see in this link:
http://en.wikipedia.org/wiki/Non-ionizing_radiation
This may also explain the difference between ionizing and non-ionizing
radiation.

Ron,
Thanks for the response. However, I'm still a bit confused (a fairly
normal state for me). ;-)
First, maybe it is just semantics, but I personally would not call
anything "well above the visible light frequencies" RF as the OP was
implying.
Finally, you say "well above the visible light frequencies and part way
through the ultra violet range".
I thought that ultra violet was -immediately- above visible blue, not
"well above".
