Godzilla, the original Rodan(s) died after being burned alive in a lava stream, so it's safe to assume that Godzilla's Atomic breath would st least injure it if not out right kill it. Also by there very nature they would be more susceptible to injury, needing a lighter body frame to get of the ground, meaning they would be more fragile than the more heavily built Godzilla.
