Radioactivity doesn't really always visibly glow. That's more of just a trope of science-fiction used to illustrate that something is radioactive, based on the idea of real-life Cherenkov radiation. Godzilla's dorsal plates and atomic breath glow based on that logic, but my point remains that Yamane never says anything about Godzilla's habitat glowing green.
