I assume you're talking about radials laying on the ground?
Rudy Severns (N6LF) has studied this with both models and field experiments
http://www.antennasbyn6lf.com/
In particular look at his presentation on tests
http://www.antennasbyn6lf.com/files/ground_system_tests.pps
To a certain extent it depends on your soil properties, but his take
home is that more shorter radials is better until you get to around 16
radials...
