I think you mean
"moiré".  Yes, it's a
problem, although most modern scanning software (starting, IIRC, with
Ofoto back in the early 1990s) has ways of reducing or eliminating these
artifacts.  I know that my Microtek scanner (about six or seven
years old) has software that does this automagically.

Try the following: do *several* scans of the image, moving the
photo (I'm assuming you have a print and you're using a flatbed scanner)
a little bit to the left or right.  Now rotate the photo, thirty or
forty-five degrees, and scan again.  One of these scans *may* be
better than the others.  As well, check your scanner's software and
documentation to see if it has any built-in
moiré-reduction capability which needs
to be either activated or tweaked.

Finally, check out
www.scantips.com. 
There may be further hints there.

Good luck!
