[Godzilla] Since Godzilla feeds on radiation, how large could a population of adult Godzillas get before becoming unsustainable?

Probably a few dozen adults. The problem is how much space they require near the earth's core that'll be used up. Nuclear and atomic weapons and power plants seemingly over charge them for a short time but the main food source is radiation from the upper mantle leaking out. A few dozen covering the lowest reaches of the sea floor would probably be the max before starvation or cannibalism sets in. Tho some smaller ones will probably nest inside nuclear reactors to absord radiation that way.
