We use labelled size markers for primer extension reactions or other 
gels where we require a marker to identify the product length.  Ambion 
(I have no affiliation with this company) sells a marker that you can 
radiolabel called the century marker.  It is a 100 bp ladder up to 500 
bp.  I have used this a few times and it works great.  Good luck!
