Galvanized can be a problem in some soils. This is the reason that galvanized 
ground rods are no longer recommended in most applications (I think ON4UN even 
has a pictured of a rotted galvanized ground rod in his book).

Copper-clad steel ground rods are more common and will generally hold up much 
better in typical soil conditions. I would assume the same would apply to 
galvanized steel and copper radial wires. I'd be careful using galvanized wire 
for radials without at first testing it to make sure it would last. It would be 
a shame to invest time and effort in a radial system just to see it rot away in 
a few years!
