Why not start off by flushing the radiator thoroughly and make a note of what comes out.

You could also have a look in the expansion tank to see what colour the water is. If it matches what you saw dripping out, then there is your problem. I agree with the post about the head gasket, but there should be secondary results like missing, or uneven running. Best to try the easy (and cheap) things first.
