Hello Jorge,
There is very little current flowing in each radial wire so the wire
size matters very little. In your example you would be much better off
with the 120 radials than 40. Keep in mind though that 120 radials is
way too many and a waste of wire.
For a great discussion on radials see:

There are a lot of other great articles on this site as well.
See you on the air..........
